Once you've decided to repaint, and before actually doing so, I'd give polishing a shot. Go get a random orbit polisher, some very fine compound, watch some YT videos, and see what you can do. It probably doesn't need a repaint just because of oxidation, and even if you can't polish it all out I bet you can get it good enough that you don't care anymore. Even having a pro do it, a couple hundred bucks vs $3k.

If it winds up not working, you were planning to repaint anyway........
