Brownell Oxpho-Blue Professional Grade Cold Blue 082-024-004

Originally developed for the occasional bluer who is not equipped to completely polish a gun prior to bluing, Oxpho Blue - because of its ease of application and remarkably superior results - has become a favorite of the professional gunsmith as well. With Oxpho-Blue, all you need do in most cases, is dampen a piece of cotton flannel and give the area a good rubbing. The chemical goes through the oil on the gun, removes thin rust and blues the steel underneath. No after-rust. For looks, the final finish was not intended to approach the beauty of the well-polished, hot-blued gun.

It has developed, however, that in the hands of a careful craftsman, not only is the Oxpho-Blue finish beautiful, but it is also more durable and weather resistant than any other known chemical finish.
