Here is the issue with paint issues. If you ride it it will get scratches and wear marks. So you take this bike and have it repainted. Six months down the road, it will have some blemishes somewhere. This one looks like a good rider. Apply some rust stopping primer on the problem areas. Follow that with some clear protection like fingernail polish. Then, don't worry about until you decide to part with it. Repaint it if you are going to part with it.
