Best Sanding Discs For Cars for Wet and Dry Sander Work

Best Sanding Discs For Cars

A strong choice of sanding discs for cars matches your sander, covers the grit range your job needs, and suits the surface work you plan to do. Dura-Gold 6-Inch Gold PSA Discs lead for automotive paint work, with pressure-sensitive adhesive and grits from 80 to For wet sanding or finer finishing, the ranked options include silicon carbide discs in 5- and 6-inch formats, while other sets offer foam pads, dust-extraction holes or a broad coarse-to-fine assortment.

Fit matters: a disc must match the sander’s pad and attachment system, not just its diameter. This guide compares the supplied specifications and highlights where each assortment fits, so you can narrow the choice for paint preparation, sanding, or polishing without assuming that every set serves the same task.

Dura-Gold 6-Inch PSA Discs are the strongest overall pick for car work because the listing specifically names automotive paint, metal, fiberglass, and primers as compatible materials. The 6-inch discs use pressure-sensitive adhesive backing for a DA sander and come in five grits—80, 120, 220, 320, and 400—with 10 discs of each. Choose another option if you need wet sanding or finer polishing grits: several hook-and-loop silicon carbide sets cover those needs more directly.

Detailed Reviews: Best Sanding Discs For Cars

Dura-Gold 6-Inch PSA Discs

#1 · Best Overall

1. Dura-Gold 6-Inch PSA Discs

  • Dimensions: 6"L x 6"W
  • Grit Material: Aluminum Oxide, Zirconia Alumina
  • Compatible Material: Wood, Automotive Paint, Metal, Fiberglass…

Best for: PSA disc bodywork sanding.

Why it ranks #1: Automotive paint, metal, fiberglass, and primers are listed as compatible; 6-inch PSA discs cover five grits from 80 to 400 for DA sanders.

Pressure-sensitive adhesive backing gives these 6-inch Dura-Gold discs a quick attachment method for a DA sander with a PSA backing plate. Five grits from 80 to 400 let automotive users move through bodywork sanding grades, while pull tabs ease removal of the protective backing layer.

The 50-disc assortment supplies ten each of 80, 120, 220, 320, and 400 grit, giving repeated stock across its coarse-to-medium range. The adhesive is described as attaching quickly and securely to a DA sander's PSA plate, so the key setup requirement is that matching plate rather than a hook-and-loop pad. Aluminum-oxide and zirconia-alumina abrasive materials are listed, with compatibility across automotive paint, metal, fiberglass, primers, plastics, and wood.

Pros
  • Six-inch discs suited to a compatible DA sander
  • PSA adhesive backing attaches to a PSA backing plate
  • Pull tab eases removal of protective backing
  • Ten discs each at five grits from 80 to 400
Cons
  • The pressure-sensitive adhesive backing requires a PSA backing plate, not a hook-and-loop pad.

Skip it if you use a hook-and-loop random orbital sander; the S&F STEAD & FAST 5-inch discs attach with hook-and-loop backing.

Choose Dura-Gold for automotive sanding on a DA sander already equipped with a PSA plate, especially when you need multiple discs at five lower grits. The adhesive format is the deciding fit consideration; it is not a hook-and-loop setup.

S&F 5-Inch Wet-Dry Discs

#2 · Best Grit Range

2. S&F 5-Inch Wet-Dry Discs

  • Dimensions: 5"L x 5"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Wood, Metal, Automotive, Plastic

Best for: Coarse-to-fine 5-inch work.

Why it ranks #2: Automotive use is listed, and the 54-piece silicon carbide assortment spans 80 to 3000 grit for wet or dry sanding on a 5-inch random orbit sander.

A grit range from 80 to 3000 gives the S&F STEAD & FAST set a useful path from rough sanding toward fine polishing. Its five-inch hook-and-loop discs fit most 5-inch random orbit sander brands, enabling automotive users to progress through grades on a familiar tool.

The mix allocates four discs each at 80, 120, and 180, six at 220, eight each at 400, 600, and 1000, and six each at 2000 and 3000. Heavy-duty silicon carbide and waterproof backing paper support wet sanding, while the reusable hook-and-loop surface allows repeated attachment and removal. The product cautions against using low-grit discs on rough or sharp edges to prevent premature tearing, an important boundary during bodywork.

Pros
  • Grits span 80 to 3000 for coarse work through refinement
  • Silicon-carbide abrasive with waterproof backing paper
  • Hook-and-loop backing supports repeated disc changes
  • Listed for most 5-inch random orbit sander brands
Cons
  • The manufacturer cautions that low-grit discs can tear prematurely on rough or sharp edges.

Skip it if you want an assortment starting at 180 with ten discs per grade; the Rvetol 5-inch 100-piece set offers that distribution.

Pick this assortment for car projects needing both rough sanding and later refinement on a 5-inch random orbit sander. Its low grades broaden the workflow, but heed the edge-tearing caution and avoid forcing coarse discs over sharp surfaces.

BerryBoi 5-Inch Foam-Backed Discs

#3 · Finest Included Grit

3. BerryBoi 5-Inch Foam-Backed Discs

  • Dimensions: 5"L x 5"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Glass

Best for: Fine finish with foam backing.

Why it ranks #3: The automotive-use listing and silicon carbide assortment extend from 180 to 5000 grit; foam-cushioned backing pads add a polishing-oriented option.

Foam-cushioned backing pads accompany this 51-piece, 5-inch wet-and-dry assortment, giving automotive sanders an included cushioned interface for polishing work. Ten grades from 180 to 5000 let users move from sanding toward mirror polishing while keeping the same hook-and-loop disc format.

The assortment lists grits 180, 320, 400, 600, 800, 1000, 1500, 2000, 3000, and 5000, covering a broad fine-sanding progression for automotive, metal, wood, and glass applications. Waterproof silicon-carbide discs support wet or dry work, and hook-and-loop backing helps speed installation on a compatible random orbital sander. The included foam-cushioned sponge backing pads add an interface for polishing tasks, although the supplied grits begin at 180 rather than very coarse stock removal.

Pros
  • Ten grits from 180 to 5000
  • Waterproof silicon-carbide discs support wet and dry use
  • Hook-and-loop backing for random orbital sanders
  • Foam-cushioned sponge backing pads included
Cons
  • The grit range begins at 180, limiting the set for very coarse initial sanding.

Skip it if you need grits below 180 for rough paint removal; the S&F STEAD & FAST set includes 80, 120, and 180.

This BerryBoi kit suits car finishers who want wet-or-dry fine sanding and included foam-cushioned pads for polishing on a compatible 5-inch orbital sander. Its 180-grit floor makes it less suited to jobs that start with aggressive material removal.

Elechiakan 6-Inch Wet-Dry Discs

#4 · 6-Inch Wet Sanding

4. Elechiakan 6-Inch Wet-Dry Discs

  • Dimensions: 6"L x 6"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Glass, Iron, Stainless Steel, Wood

Best for: Six-inch wet sanding setup.

Why it ranks #4: This 6-inch silicon carbide set is explicitly described for auto and wet sanding, though the supplied specifications do not state its grit assortment.

A six-inch wet-and-dry silicon-carbide disc set includes a foam buffering interface backing pad, giving automotive users an included interface for sanding and polishing work. The hook-and-loop format supports disc changes on a compatible sander, while waterproof abrasive can be rinsed during wet sanding to clear debris.

Elechiakan describes the silicon-carbide material as resisting dulling and supports both wet and dry use; wet sanding can rinse away debris to help prevent clogging and reduce dust. The 70-piece listing also names a foam buffering interface backing pad, adding a supplied interface component to the sanding setup. Its six-inch size points to a matching sander pad, and stated compatible materials include glass, iron, stainless steel, and wood. The listing does not specify the grit assortment in the supplied details.

Pros
  • 70-piece listing for six-inch wet-and-dry sanding discs
  • Silicon-carbide abrasive specified as resistant to dulling
  • Wet sanding can rinse debris to help prevent clogging
  • Foam buffering interface backing pad included
Cons
  • The supplied product details do not specify the included grit grades.

Skip it if you need a clearly listed grit progression for your job; the Rvetol 6-inch set specifies five grades from 1000 to 5000.

Consider Elechiakan for six-inch wet-or-dry sanding where silicon carbide, rinsing debris, and an included foam interface suit the workflow. Since the supplied listing details do not identify grit grades, it is a weaker fit when a precise progression is essential.

Rvetol 5-Inch 8-Hole Discs

#5

5. Rvetol 5-Inch 8-Hole Discs

  • Dimensions: 5"L x 5"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Wood, Metal, Leather, Rubber, Plastics…

Best for: Broad-grit 5-inch sanding.

Why it ranks #5: The 100-piece silicon carbide set includes ten grits from 180 to 3000 and supports wet or dry sanding, but automotive compatibility is not specified.

Ten grits spanning 180 to 3000 give this 100-disc Rvetol assortment a broad progression for automotive sanding, surface refinement, and polishing. The 5-inch, eight-hole discs attach by hook and loop, enabling a compatible orbital sander user to move through grades without changing disc size or backing style.

Each grit has ten discs, so the sequence from 180, 240, and 320 through 3000 includes stock for both earlier sanding and finer work. Waterproof paper and silicon-carbide abrasive support wet or dry use, while the eight-hole pattern is suited to compatible dust-extraction setups. Hook-and-loop backing allows quick changes on a 5-inch orbital sander; listed compatibility also includes angle grinders, and the assortment covers materials including metal, plastics, glass, and stone.

Pros
  • 100 discs across ten grits from 180 to 3000
  • Eight-hole pattern for compatible dust extraction
  • Waterproof silicon-carbide paper for wet or dry use
  • Hook-and-loop backing; listed for orbital sanders and angle grinders
Cons
  • The lowest supplied grit is 180, so it lacks the coarser grades some repair jobs require.

Skip it if you need grits below 180 for rough removal; the S&F STEAD & FAST 5-inch set begins at 80.

This set fits DIYers or professionals seeking a large 5-inch assortment for wet-or-dry sanding and polishing on compatible tools. Choose another range if your car repair workflow starts with very coarse sanding, since this assortment begins at 180 grit.

POTUINOM 5-Inch Fine Discs

#6

6. POTUINOM 5-Inch Fine Discs

  • Dimensions: 5"L x 5"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Multi-purpose

Best for: Eight-hole fine wet sanding.

Why it ranks #6: The 8-hole, hook-and-loop silicon carbide discs offer 1000 to 5000 grit for fine polishing, with named compatibility for several 5-inch orbital sanders.

Five fine grades from 1000 to 5000 and an eight-hole layout make this 50-disc POTUINOM set a focused option for wet-or-dry automotive finishing. The 5-inch hook-and-loop discs enable compatible random orbital sander users to refine surfaces while using a format intended for dust extraction.

The set includes ten discs each at 1000, 1200, 2000, 3000, and 5000 grit, providing repeat stock for fine sanding and polishing rather than coarse preparation. Silicon-carbide abrasive is electro-coated, and the discs are specified for wet use as well as dry sanding. Eight pre-punched holes support dust extraction on compatible tools; listed devices include several 5-inch random orbital and palm sanders, so the pad and hole arrangement should match the sander being used.

Pros
  • 50 discs across five grits from 1000 to 5000
  • Ten discs at each grit
  • Silicon-carbide abrasive with electro-coated construction
  • Eight holes and hook-and-loop backing for compatible sanders
Cons
  • The assortment starts at 1000 grit and cannot cover coarse sanding or paint removal.

Skip it if you need coarse grits for initial bodywork sanding; the S&F STEAD & FAST set includes grades down to 80.

This POTUINOM set fits car owners and finishers working on fine wet-or-dry sanding with a compatible 5-inch, eight-hole sander. It offers a concentrated polishing range, so use a separate coarse assortment for preparation or deeper correction.

Rvetol 6-Inch Fine Discs

#7

7. Rvetol 6-Inch Fine Discs

  • Dimensions: 6"L x 6"W
  • Grit Material: Silicon Carbide
  • Compatible Material: Automotive, Wood, Metal

Best for: Fine wet-sanding finish work.

Why it ranks #7: Waterproof 6-inch silicon carbide discs cover 1000 to 5000 grit and fit random orbital sanders, making this set more suited to fine polishing than paint removal.

Five silicon-carbide grits from 1000 to 5000 make this 6-inch set a focused choice for fine wet-or-dry sanding and polishing. It gives automotive finish workers several steps for refining a surface, with ten discs at each grade so a chosen grit can stay in rotation across a project.

The waterproof construction supports wet sanding, while the hook-and-loop backing makes attachment to a random orbital sander straightforward. Its 1000, 1500, 2000, 3000, and 5000 grit sequence serves fine refinement rather than initial heavy material removal, and ten discs per grit provide repeat stock at each step. At six inches, it suits a matching orbital-sander pad; silicon carbide is specified for automotive, wood, and metal applications.

Pros
  • Five fine grits from 1000 through 5000
  • Ten discs supplied at each grit
  • Waterproof discs support wet and dry sanding
  • Hook-and-loop backing for random orbital sanders
Cons
  • The assortment starts at 1000 grit, so it does not cover coarse paint or material removal.

Skip it if you need coarse sanding before finishing; the S&F STEAD & FAST 5-inch set includes grits down to 80.

Choose this Rvetol set for automotive finishers who need multiple fine grades for wet-or-dry polishing with a six-inch random orbital sander. Its 1000-grit starting point makes it a finishing-focused choice, not a complete coarse-to-fine sanding assortment.

NOOKEYA 5-Inch 8-Hole Discs

#8

8. NOOKEYA 5-Inch 8-Hole Discs

  • Dimensions: 5"L x 0.01"W
  • Grit Material: Aluminum Oxide
  • Compatible Material: Art, Wood, Aluminum Alloy, Fiberglass…

Best for: Coarse orbital sanding changes.

Why it ranks #8: The 5-inch, 8-hole aluminum oxide discs cover coarse grits from 60 to 320 and list painted surfaces among compatible materials, but not automotive use specifically.

Printed grit numbers on the back make this 52-disc NOOKEYA set easier to sort during sanding changes. Its 5-inch, eight-hole hook-and-loop discs cover grits 60, 80, 120, 220, and 320, enabling coarse-to-medium sanding on a compatible random orbital sander.

The eight-hole layout is specified for dust collection, which can support a cleaner sanding workflow when paired with a compatible setup. Hook-and-loop backing makes disc installation and removal quicker, and the printed grit labels help identify the next grade without guessing from the abrasive face. Aluminum-oxide abrasive is described as anti-static and durable; with grades topping out at 320, this assortment focuses on earlier sanding stages rather than very fine automotive polishing.

Pros
  • 52 discs in five grits from 60 to 320
  • Grit labels printed on disc backs
  • Eight pre-punched holes for dust collection
  • Hook-and-loop backing for quicker changes
Cons
  • The highest listed grit is 320, so the set does not include fine polishing grades.

Skip it if you need 1000-to-5000-grit wet-or-dry finishing discs; the POTUINOM 5-inch set covers that range.

This NOOKEYA assortment suits users doing early-stage sanding on a 5-inch orbital sander, especially when quick grit identification and dust-collection holes matter. Its range ends at 320, so plan on separate finer discs for paint finishing or polishing.

3M Xtract Cubitron II Net Disc

#9 · Best Dust Extraction

9. 3M Xtract Cubitron II Net Disc

  • Dimensions: 5"L x 5"W
  • Grit Material: Ceramic
  • Compatible Material: Industrial,metal

Best for: Dust-controlled industrial sanding.

Why it ranks #9: Its net backing is described as extracting up to 99% of sanding dust, and ceramic abrasive suits random orbital sanders; the listing targets industrial use.

A net backing paired with 3M Precision-Shaped Grain is specified to extract up to 99% of sanding dust, making this 5-inch disc a compelling fit for dust-conscious shop work. The assorted grades from 80plus to 320plus enable a sanding progression on compatible random orbital sanders.

The multipack includes two discs each of 80plus, 120plus, 180plus, 220plus, 240plus, and 320plus, supplying several grades for fleet or plant maintenance. Its net construction enables dust extraction through the disc, while the product description connects that pattern with a cleaner work environment and more parts finished per disc. Ceramic abrasive and compatibility with random orbital sanders define the setup. 3M labels this industrial and occupational product for trained workplace customers, a relevant use boundary for car enthusiasts.

Pros
  • Net backing enables up to 99% dust extraction
  • 3M Precision-Shaped Grain technology
  • Six grades from 80plus to 320plus, two discs each
  • Ceramic abrasive for compatible random orbital sanders
Cons
  • 3M labels the product for trained industrial and occupational workplace customers.

Skip it if you are a casual home user seeking a consumer-labeled assortment; the BerryBoi 5-inch wet-and-dry set lists automotive use.

This 3M disc suits trained shop users sanding automotive or maintenance parts with a compatible random orbital sander and dust extraction. Its workplace-use labeling and grade range through 320plus are key boundaries when choosing it for a car project.

Pukamam 3-Inch Disc Set

#10

10. Pukamam 3-Inch Disc Set

  • Dimensions: 3"L x 3"W
  • Grit Material: Medium
  • Compatible Material: Wood,metal

Best for: Small-area drill sanding kit.

Why it ranks #10: This 3-inch silicon carbide set spans 60 to 10000 grit and includes polishing accessories, but its listed compatible materials are wood and metal rather than automotive.

A 174-piece package pairs 3-inch wet-or-dry discs spanning 60 to 10000 grit with drill sanding pads and polishing accessories. That combination enables users to handle varied small-area sanding and polishing tasks with a compact disc size and several listed attachment accessories in one kit.

The 160 silicon-carbide discs include ten pieces at each grit from 60 through 10000, giving a particularly wide progression for work from material removal to fine polishing. The package also lists three hardnesses of polishing pads, wool pads, drill sanding pads, foam sponge pads, and metal shanks. Those accessories support drill-based sanding and polishing workflows, while the 3-inch disc format is suited to smaller working areas than a standard 5- or 6-inch disc setup.

Pros
  • 160 discs span grits 60 to 10000
  • Ten discs at each listed grit
  • Wet-or-dry silicon-carbide abrasive
  • Includes drill sanding pads, polishing pads, wool pads, and foam pads
Cons
  • The 3-inch disc size provides less sanding coverage per pass than larger discs.

Skip it if you need broad coverage with a 5-inch orbital sander; the Rvetol 5-inch 100-piece set is sized for that workflow.

Choose Pukamam for detailed automotive work, small areas, or a drill-accessory kit that combines sanding and polishing supplies. The 3-inch discs and listed shanks suit compact tasks, but they cover less surface per pass than larger sanding discs.

Avoiding common disc-fit and surface problems

A disc that fits the diameter but not the attachment or hole pattern can frustrate a car-sanding job. The listings distinguish PSA adhesive backing, hook-and-loop backing, and 8-hole layouts; check the backing plate and dust ports on your sander before choosing. For example, Dura-Gold 6-Inch PSA Discs are designed for a PSA backing plate, while many of the other listed discs use hook-and-loop attachment.

The 5-inch Rvetol and POTUINOM sets specify eight holes, but that does not establish fit with every sander. Another failure mode is using a coarse disc on a sharp edge: S&F specifically cautions that low-grit discs can tear prematurely on rough or sharp edges.

Use the listing’s grit guidance as a starting point, and avoid treating a wide grit range as proof that every grit is appropriate for every panel or finish.

Wet sanding and dust extraction are different priorities

Wet sanding and dust extraction address different working conditions, so a disc optimized for one should not be assumed to provide the other. Several silicon carbide sets—including S&F 5-Inch Wet-Dry Discs and BerryBoi 5-Inch Foam-Backed Discs—are described for wet and dry use. Wet sanding can rinse away debris, but the supplied listings do not establish that every sander or backing pad is suitable for wet operation; check tool guidance before using water.

By contrast, the 3M Xtract Cubitron II Net Disc is designed around a net backing and claims up to 99% dust extraction, but its listing identifies industrial and metal uses and workplace customers. Consider the working method first: choose an explicitly wet/dry disc for wet finishing, or a compatible dust-extraction setup for dry sanding.

Neither feature replaces checking the sander’s fit requirements.

How to Choose Car Sanding Discs

Match diameter and backing

Start by matching the disc diameter and attachment style to your sander’s backing plate. This set includes 3-, 5-, and 6-inch discs; most are hook-and-loop, while Dura-Gold 6-Inch PSA Discs use pressure-sensitive adhesive backing for a DA sander. Several 5-inch discs also specify eight holes, including the Rvetol and POTUINOM assortments.

The listings do not establish universal fit across every tool, so check your pad size, attachment surface, and hole pattern before buying. A 5-inch orbital sander user should focus on 5-inch options; a compatible 6-inch DA setup may favour Dura-Gold for paint preparation.

The 3-inch Pukamam set is the specialty choice for smaller areas or its included drill accessories.

Choose grits for the task

Look for a grit assortment that covers the stages you actually plan to do, rather than choosing by the highest grit alone. Dura-Gold 6-Inch PSA Discs run from 80 to 400, while S&F 5-Inch Wet-Dry Discs cover 80 to 3000 and BerryBoi 5-Inch Foam-Backed Discs span 180 to Pukamam’s 3-inch set extends from 60 to 10000, but it is not listed as an automotive product.

Coarser grits suit more aggressive removal tasks, while fine grits are aimed at finishing and polishing; the listings do not provide a universal grit sequence for car paint. Buyers doing paint preparation may favour Dura-Gold’s automotive-specific range, while wet-finishing buyers may prefer one of the finer silicon carbide sets.

Select abrasive and wet/dry use

Check abrasive type and stated use, especially if wet sanding is part of the plan. Silicon carbide wet/dry choices include S&F, BerryBoi, and the Rvetol assortments; the listed Dura-Gold discs instead use aluminum oxide and zirconia alumina. NOOKEYA’s aluminum oxide discs list painted surfaces as a compatible material, but do not specify wet use.

These differences matter because a product’s material and stated use should guide the task, not assumptions based on appearance or grit number. Buyers who want wet sanding and fine polishing have several silicon carbide options; buyers preparing automotive paint with a DA and PSA pad may prefer Dura-Gold.

For dust control during dry sanding, the 3M net disc claims up to 99% extraction, but its listing is oriented toward industrial and occupational use.

Which sanding discs should I choose for my car?

For automotive paint preparation with a compatible 6-inch PSA DA sander, choose Dura-Gold 6-Inch PSA Discs: automotive paint is a named compatible material, and the set covers 80 to 400 grit. For wet sanding with a 5-inch random orbit sander, S&F 5-Inch Wet-Dry Discs offer a stated 80-to-3000 range and explicitly list automotive use. If your focus is fine polishing and you want foam-cushioned pads, BerryBoi 5-Inch Foam-Backed Discs reach 5000 grit.

Choose Elechiakan 6-Inch Wet-Dry Discs if 6-inch wet sanding and auto use matter, but note the supplied specifications do not state its grits. Before ordering any option, confirm disc diameter, attachment type, and hole layout against your sander.

Frequently Asked Questions

What grit should I use to sand car paint before repainting?

Choose grit according to the preparation stage and the paint or primer instructions; there is no single grit for every repaint. The Dura-Gold set offers 80, 120, 220, 320, and 400 grits and specifically lists automotive paint and primers as compatible materials. Confirm the required grit for your particular repair before sanding.

Can I use wet sanding discs with my random orbital sander?

Some listings specifically pair wet-dry discs with random orbital sanders, but that alone does not confirm that your sander is suitable for wet operation. S&F’s 5-inch wet-dry discs list automotive use and a stated 80-to-3000 grit range. Check the sander and disc instructions, and match the diameter and attachment before use.

How do I match sanding disc holes and backing to my car sander?

Match the disc diameter, attachment type, and hole layout to your sander and backing pad. For example, some listed 5-inch discs use hook-and-loop attachment and an 8-hole pattern, while Dura-Gold’s 6-inch discs use pressure-sensitive adhesive backing. Do not assume a disc will fit based on diameter alone.

Which discs are listed for wet sanding automotive work?

S&F’s 5-inch wet-dry discs explicitly list automotive use and cover a stated 80-to-3000 grit range. Elechiakan’s 6-inch wet-dry discs also list auto use, though their supplied specifications do not state the grits. Check the attachment and size against your sander before choosing either set.

Which option suits fine polishing?

For fine polishing with foam cushioning, the BerryBoi 5-inch foam-backed discs reach 5000 grit. Other hook-and-loop silicon carbide sets also cover finer grits, including listings that reach 5000, but compare their backing and fit with your sander. Choose based on the finish task and the grit range stated for the specific set.

Final Words

For automotive paint preparation, choose the Dura-Gold 6-inch PSA discs if your DA sander accepts PSA backing: the listing names automotive paint, metal, fiberglass, and primers, and the set spans 80 to 400 grit. For wet sanding, consider S&F’s 5-inch set for its stated automotive use and 80-to-3000 range, or BerryBoi for foam-backed polishing up to 5000 grit. Before ordering, verify diameter, attachment, and hole layout.
