SurfPrep Film abrasive sheets are amazing for quick stock removal. Film was created to level sand, remove saw marks, sand through old finish and deep scratches, or anything that requires quick removal. Film resists tearing and leaves a uniform scratch pattern. The white ‘sacrificial stearate’ prevents loading of material while sanding. These sheets are made with a modified open-coat aluminum oxide grain. Always use a Pad Saver when sanding with these sheets on your sander. There are 100 sheets of sandpaper per box.
