Birchwood Casey Brass Black 90 ml

Birchwood Casey Brass Black 90 ml is a fast-acting liquid used to blacken or antique brass, copper, and bronze parts.

Application: It is easy to apply with no dimensional change to the part and is often used for touch-ups or marking.
Uses: While common for gunsmiths to mark cartridge cases, it is also used for a wide range of other items including nameplates, plaques, castings, and sculptures.
