Wet or dry, a Norton SandWet Sanding Sponge ensures you’ll make a smooth surface. This sanding sponge has a wet/dry paper on two surfaces, while its malleable composition allows it to conform to curved or flat surfaces, details and more. When finished, simply rinse and reuse. This wet-sanding method also cuts down on dust in the air. Ideal for wood, metal, fiberglass and painted surfaces.
