3M Scuff Sanding Sponge

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.nDesigned Specifically for Scuff SandingIdeal for use during Stage 4 of our 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 our 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.
