Aluminum oxide is a sharp, very hard abrasive for cleaning, stripping, and etching on most materials. Use for surface preparation to produce a matte finish. Aluminum oxide is a long-lasting reusable media which does not react with surfaces.

Choose the appropriate grit for desired finish: [46 Grit - Coarse - 0.0083" to 0.0165" in.] [54 Grit - Coarse - 0.0070 to 0.0139 in.] [60 Grit - Coarse - 0.0059 to 0.0117 in.] [70 Grit - Medium Coarse 0.00555 - 0.0100] [80 Grit - Medium Coarse - 0.0041 to 0.0083 in.] [90 Grit - Medium Coarse - 0.0033 - 0.0071] [100 Grit - Medium Fine - 0.0025 to 0.0059 in.] [120 Grit - Medium Fine - 0.0021 to 0.0049 in.] [150 Grit - Fine - 0.0017 to 0.0041 in.] [180 Grit - Fine - 0.0021 to 0.0035 in.] [220 Grit - Very Fine - 0.0017 to 0.0029 in.]
