![]() A double-strength blueing solution designed for blueing the highly polished steel parts and hardened steels containing nickel and chrome alloys. Super blue is the blackest blue but is not as easy to use as Perma Blue to get an even, non-streaky finish. Use caution to confine the solution to an area to be reblued as it will have an effect on the existing blue. Usually one application is sufficient followed by an application of Sheath to enhance and protect the finish. Birchwood Casey R2- Super Blue Liquid Gun Blue is no longer avail.
