3M Pro Grade Precision Dual Angle Sanding Sponge

3M Pro Grade Precision Dual Angle Sanding Sponges are ideal for sanding painted surfaces and resists loading which allows for larger sanding coverage. Sponge lasts 5X longer* compared to 3M conventional sandpaper. Also has 33% increased cut* over 3M conventional abrasive of comparable grit. Can be used wet or dry on all surfaces. Rinse and reuse. For the best results, sand with the grain of the surface and work through a sequence of grits, from coarse to very fine, skipping no more than 1 grit between each sanding step (other grits not included). 2.875" X 4.5" X 1"
