Sharp-Edged Silicon Carbide Self-Lubricating Petroleum Base
The very best abrasive compound for "hard fitting" two pieces of
steel. Stands up to continued fitting even on hardened and
heat-treated steel. Silicon carbide grit combined with a thick, long
lasting lubricant breaks down into smaller and smaller
sharp-edged particles to keep cutting longer than aluminum oxide
compounds. For use on steel only. Remove with solvent.
