I have a '55 that is an older restore and the paint(appears to be an amateur job) is in good shape over all but I have noticed some spots that are showing small bubbling(signs of rust), other areas where the paint has small cracks with rust showing through(around the trunk opening for example), some spots that have what appears to be over-spay from the white onto the red, as well as a spot over the rear passenger side fender where the paint is creased, looks like a bad bondo job. Here in lies the question. I can live with the bad bondo job as it isn't obvious unless you walk up and investigate, but I am definitely concerned about the rust spots. What is the best, cost effective approach to these? This is my daily driver and I want this car to last and look good while doing so. I am just not sure how to address the issues without doing a complete strip down and new paint job. Thus why I am here asking for advise. I am not a painter so I would either have to DIY it or find a reasonable painter to help with it.
