Micro-Mesh is a unique cushioned abrasive capable of giving very fine & very controlled scratch patterns. The grits range from 1500 to 12000. The 1500 is slightly more coarse than a conventional 600 grit sandpaper & the 12000 will leave scratch patterns that cannot be detected by the human eye. Micro-Mesh abrasives can polish to an optically clear, reflective state or through the use of a more coarse grit, leave a matte or satin finish. Excellent product to use as a final rub for water-based finishes. This kit is designed for craftsmen to replace the use of steel wool, rottenstone, or pumice. May be used on bare or finished wood. An excellent way to spot match finishes. Can be used wet or dry to achieve matte, satin, or high gloss finishes.
