Lucas Oil 10880 Gun Metal Polish & Tumbler Media Additive 16 oz

The Lucas Oil Gun Metal Polish & Tumbler Media Additive (item 10880) is a versatile acid- and ammonia-free liquid polish designed to clean, brighten, and protect factory firearm finishes without harming primers or reloading brass. The 16 oz bottle delivers a low-odor formula that safely lifts surface stains and rust with minimal rubbing while leaving a protective film behind on treated metal.

This polish is safe for use on common factory gun finishes including blue/blued steel, nickel, stainless, aluminum, and brass, making it equally at home on handguns, long guns, and the reloader's bench. Note: it is not for use on cold bluing.

Beyond direct polishing, the same liquid doubles as a tumbler media additive. Add 1 oz per quart of tumbling media to brighten and clean cartridge cases and small parts during vibratory or rotary tumbling. The ammonia-free chemistry will not etch primers or brass, and there is no harsh chemical smell to contend with in the workshop.

Made by Lucas Oil, the 16 oz bottle is a shop staple for anyone restoring heirloom firearms, refreshing daily-carry guns, or processing range brass in bulk.
