Birchwood Casey Aluminum Black Touch Up 3 oz Metal Finish

The Birchwood Casey Aluminum Black Touch Up is a fast-acting, room-temperature black metal finish trusted by gunsmiths and industry to blacken aluminum parts. Packaged in a 3 oz bottle, this liquid restores scratched and marred areas quickly with no dimensional change, leaving a durable dark finish that varies from deep gray to black depending on the alloy being treated.

Easy to apply and working by chemical reaction rather than paint, Aluminum Black bonds to bare aluminum for a long-lasting touch up on firearm components, name plates, plaques, trophies, and other engraved items. Simply apply, allow the reaction to occur, and wipe clean. The final appearance can be further protected by sealing the finished surface with a clear coat, wax, or oil.

A staple of any gunsmith's bench, this Birchwood Casey metal finish is ideal for refreshing the appearance of aluminum firearm parts that have lost their original factory-black finish through handling, wear, or use. The 3 oz bottle provides ample supply for multiple touch-up applications.
