Lucas Gunmetal Polish & Tumbler Media Additive

Used and recommended by major firearms manufacturers, Lucas Gunmetal Polish and Tumbler Media Additive cleans and polishes factory firearm finishes like steel, nickel, stainless, aluminum, and brass. Its acid- and ammonia-free formula safely removes stains and rust from metals with no hard rubbing—while protecting treated surfaces from oxidation and tarnishing. The compound is great for use as a tumbler media additive to remove oxidation, powder residue, fingerprints, and other contaminants, leaving brass and nickel cases bright and shiny. Use with walnut shell or corncob tumbling media to reduce cleaning time by up to half, compared to using plain media alone. Lucas Gunmetal Polish and Tumbler Media Additive will not damage primers or brass and does not smell. It's available in multiple sizes. Show Less
