Is their any kind of finish that can be applied to a stainless steel firearm, specifically a revolver? I am really interested in getting a S&W 625, but am not a fan of stainless guns. More of a blued steel man myself. Can something like Dura Coat or something similar be applied to stainless steel? For some reason I am intrigued with the possibility of a OD green finish. I'm just curious and appreciatte any replies.
