Choosing a Grade for Auto Body Work
80+ – paint removal and rough filler shaping
120+ to 180+ – filler shaping and featheredging
220+ to 320+ – primer sanding and prep
400+ – final prep before paint and blending
The multi-hole Clean Sanding pattern is built for dust extraction, and Hookit hook-and-loop backing changes out quickly on a 6 in backup pad. 3M states the precision-shaped grain cuts at least 30% faster and lasts at least 30% longer than conventional ceramic abrasives.
