Birchwood Casey 13432 Super Blue Liquid Gun Blue 32 oz Bottle

The Birchwood Casey Super Blue Liquid Gun Blue is a double-strength blueing solution formulated for rebluing highly polished steel parts and hardened steels containing nickel and chrome alloys. Sold as the blackest blue in the Birchwood Casey line, it is a go-to for touch-up and restoration work on firearms.

This 32 oz plastic quart bottle provides plenty of solution for multiple jobs. The liquid is applied directly to the metal surface being reblued. Use caution to confine the solution to the area being reblued, as it will have an effect on any existing blue finish on surrounding metal.

Super Blue is not formulated for stainless steel.
