I'm ok leaving it as is until you said you see some signs of oxidization. Then I am in team repaint. If it is a keeper, then the rainbow of doing whatever color you want to it is there for the takings.

I have a frame that was made by an extremely well thought of builder and there was clear signs of oxidization and rusting under the paint. I had it redone with the Groody Brothers when they were early in their business (we're friends and I'd visit their shop back then), when they stripped and lightly media blasted, there was clear signs of pitting in some locations of the tubing. So I feel justified and like I saved the frame too. Mark's (Groody Brothers) skills are even better now then back then so I'd highly recommend him if you went that route. He's doing it out of Topeka, KS now.

I also have a lugged Trek road bike that all sorts of chips and scratches, but no rust is really showing, so I just carry on as is until something would prompt me to do so I've certainly approached this problem from both directions.
