3M 7010328055 Performance Sanding Sponge 100 Grit

Product Description

The 3M 7010328055 is a silicon carbide-coated sanding sponge engineered for hand sanding applications in automotive body repair. At 100 grit, it is sized and textured for Stage 3 body filler shaping — removing high spots and contouring the filler to match the surrounding panel. The sponge construction resists clogging, extending usable work life compared to standard sheet abrasives. It arrives ready to use straight from the package with no cutting or prep required. Licensed automotive technicians and body shop professionals reach for this sponge during the rough shaping phase before transitioning to finer grits.

This sponge is intended for dry hand sanding on automotive body filler during the shaping stage of a repair. After 100 grit shaping is complete, follow with 180 grit sandpaper to refine the scratch pattern and prepare the surface for glaze coat or spot putty adhesion. The compact 1-inch by 2-5/8-inch format fits comfortably in the hand and conforms to moderate contours, making it practical for both flat panels and gently curved body sections. Sold individually, minimum order quantity is 12 units per order.

Compatibility

Designed for hand sanding automotive body filler during rough shaping stages. Suitable for use with standard polyester and lightweight body fillers on automotive panels.

Installation Notes

Use dry, by hand, on cured body filler only. Do not use on bare metal or primer without confirming the grit is appropriate for those substrates. After completing the 100 grit shaping pass, follow with 180 grit sandpaper before applying glaze or spot putty. Dispose of sponges when mineral loading or sponge breakdown reduces cutting performance.
