Birchwood Casey Brass Black Touch-up-32oz

The Birchwood Casey Brass Black Touch-up 32oz is a fast-acting liquid finish designed specifically for blackening and antiquing brass, copper, and bronze components without causing any dimensional change. This product is widely utilized by gunsmiths, armorers, and reloaders for its reliable results in various metallurgical applications requiring controlled darkening.

The touch-up solution comes in a convenient 32-ounce container, providing ample volume for both bench work and field maintenance across multiple projects. Its straightforward application process requires no masking or complex prep work, ensuring a smooth finish without dimensional buildup or surface irregularities. To enhance the final appearance, it is recommended to apply a clear protective coat of finish wax or light gun oil, which seals the blackened surface and prevents oxidation.

This product is ideal for professional gunsmiths, ammunition reloaders, and tactical equipment custodians who perform custom refinishing or maintenance on brass fixtures, sights, and scope bases. The fast-acting chemistry minimizes application time while delivering a uniform matte-black or antique patina suitable for both functional components and aesthetic restoration work.
