3M Green Corps sanding discs help you get the job done right the first time for auto body work including paint stripping, rust removal and shaping body filler. Our discs are made with Green Corps abrasives, a blend of minerals that cut fast and last a long time. Green Corps abrasives are built on heavy, highly durable D and E weight backing for sanding paint, metal and fiberglass. Designed for automotive power sanding, our discs are meant for use with a dual action orbital sander. These abrasive discs work great with Bondo Body Filler.
