KleenBore GB2 Black Magic Gun Blue Liquid, 2 Ounce Bottle

Black Magic is a premier, high performance cold bluing solution, previously available only to gunsmiths, that produces a deep, penetrating action to restore worn or scratched gun metal to a like-new finish. It’s the choice of many major firearms manufacturers for touching up guns before they leave the factory. Packaged in a container with a child-resistant cap and expert, easy-to-follow instructions.
