Brownells Silicon Carbide Abrasive Compound 800 Grit is the best abrasive compound for precise hard fitting of two pieces of steel. It 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. The compound comes in a 4 fl. oz. (118 ml) container.
This product is for use on steel only and should be removed with solvent. The self-lubricating petroleum base formula delivers extended cutting action through its unique particle breakdown, making it ideal for gunsmithing applications requiring precision metal-to-metal fitting and finishing work.
