Our 3M™ Scuff Sanding Sponge is designed to make touching up curves, contours, corners and hard to reach areas easier. Designed for hand sanding tasks, use this 3-2/3 x 9-inch abrasive to hand sand primer and scuff the blend area prior to applying base coat and clear coat. After sanding primer, refine with 400 or 600 grit sandpaper, and then apply paint per manufacturer’s recommendations.
