I have inherited a S&W revolver that is in excellent shape, except for a few minor spots along the barrel and a fine line around the cylinder. Has anyone had any success with some sort of polishing product that could help me improve the finish? I have quite a bit of experience with this kind of stuff for auto finishes, and I imagine there's a similar product out there for gun finishes. I have no idea what it is or where to get it, though.
Any suggestions?
