3M has innovated auto body sanding yet again with 3M™ Blue Sandpaper. This ceramic mineral blend provides best-in-class performance. The result – reduced prep time. Blue cuts 50% faster than conventional abrasives due to microreplicated grains which wear evenly and allow you to get more work done with less sheets.
