Birchwood Casey Brass Black Metal Touch-Up 3 oz Bottle

The Birchwood Casey Brass Black Metal Touch-Up is a fast-acting liquid chemical finish used by gunsmiths and industry to blacken or antique brass, copper, and bronze parts. Packaged in a handy 3 fl. oz. (89 ml) bottle, this Birchwood Casey classic applies easily with no dimensional change to the treated part, making it a go-to choice for touching up firearm hardware, refinishing brass components right at the bench, or aging new pieces to an antique black. Final color varies slightly depending on the base alloy.

Brass Black is also excellent for permanently marking reloaded cartridge cases, allowing reloaders to identify specific lots or headstamp changes at a glance. Beyond the reloading bench, the same liquid works equally well for blackening name plates, plaques, castings, sculptures, and other home, workshop, and hobby projects where a clean antique finish on non-ferrous metals is the goal.

This listing is for a single 3 oz bottle of Birchwood Casey Brass Black Metal Touch-Up, ready to add to your gunsmithing bench or reloading kit.
