I originally bought a mini-14 ranch model in stainless steel. I now regret buying the stainless version, and would like a gun with a blued finish. I saw somewhere on this website a link to a website that made a lot of Mini accessories and customized Mini's, and there they reccomended Gun Kote, saying that it is 40 times more durable than blued. can i apply this myself, or should i get a smith to do it? or, could i send it to the factory and have it refinished there? any other options?
