Super Blue Liquid Gun Blue 3 fl oz Birchwood Casey

Description

Super Blue Liquid Gun Blue is a double-strength blueing solution for blueing highly polished steel parts and hardened steels containing nickel and chrome alloys (except stainless). Super Blue is the blackest blue. Apply chemical cold using cotton swabs, synthetic brush or sponge. We recommend using Super Blue if the metal is over burnished from excessive polishing, the pores of steel become too tight, or if the metal has a high amount of nickel or chrome alloys in it.
