What is Scuff Sanding?
Instead of sandpaper, which is used for stripping paint or smoothing filler during auto body work, the 3M™ Scuff Sanding Sponge is designed for scuff sanding — a less aggressive job where instead of sanding down to the bare material, you simply add a "scuff" to the primed or coated surface. This process essentially leaves the surface slightly textured. Scuff sanding is often necessary because most modern base and clear coat paint systems rely on a chemical bond for strength and durability. These systems may not be able to establish this chemical bond with your existing surface. Using the 3M™ Scuff Sanding Sponge you create a "mechanical" bond — a scuff — which essentially gives the base coat or clear coat paint system a series of edges to adhere to. The end result is a smooth, long-lasting and professional grade finish for your vehicle.

Designed Specifically for Scuff Sanding
Ideal for use during the Finish stage of 3M™ Body Repair System, the 3M™ Scuff Sanding Sponge is designed for scuffing base, primed, or painted surfaces during auto body painting. This sponge features 3M non-fibrous aluminum oxide abrasive on a durable nylon backing. The entire pad is resin coated, so neither the non-woven backing nor the abrasive will deposit tiny particles on the surface, helping to ensure a smooth finish. The pad is ideal for scuff sanding, and is also suitable for removing light surface rust. It can be used wet or dry and rinses clean for repeat use.

About the 3M™ Body Repair System
Even a small repair can seem complex at first. So 3M's Body Repair System simplifies the entire automotive body repair process by dividing it into four stages:

Stage 1 — Prepare. This stage includes pulling dents, removal of paint and rust and efficient, effective masking of the area.

Stage 2 — Fill. This stage involves patching holes with reinforced filler and smoothing and shaping filler before painting.

Stage 3 — Paint. This stage includes painting the area and blending and smoothing primer and paint.

Stage 4 — Finish. The final stage for showroom-grade results: removing small defects, sealing and polishing clear coats and other painted surfaces.

3M supplies premium products such as abrasives, tapes, body fillers and tools for every stage. This system helps you work easily, efficiently and successfully across the entire body repair process.
