Norton SandWet 9 in. L X 3 in. W 400 Grit Silicon Carbide Sanding Sheet 6 pk

Rely on the SandWet T401 fine grit waterproof sheet and its strong resin bond for wet applications. The JIS graded ultra fine silicon carbide abrasive and durable B-weight waterproof latex paper backing means you get the finish you expect from a fine grit, with a resistance to curling due to humid conditions. The paper works well on Black finishing metal projects such as stainless steels, aluminum, brass, bronze, titanium, super alloys and soft carbon steels as well as wood, fiberglass and composites.
