I have a Uberti, (sorta) copy of an 1873 colt single action army. The frame has a faux color case hardened finish and the barrel, cylinder and backstrap are finished in a bright, polished, charcoal blue finish. The finish is almost an electric blue color and pretty. The problem is that the blue rubs off after handling the gun for a few times, leaving an ugly gray metal exposed. Is there anything that can be done, other than "just don't handle the gun".
