3M Precision Shaped Grain Sandpaper is a premium abrasive sheet that is built specifically for hand sanding on jobs such as shaping auto body filler or putty. 3M's Precision Shaped Grain is designed with sharp, angular structures that continuously fracture to form sharp points and work harder as you sand. As a result, 3M's Precision Shaped Grain Sandpaper lasts 5X longer than conventional 3M abrasives. 7100159938 - 00051131030763
