I think it’s easier to strip paint off than deal with rust but I also very well understand your puzzle as mine is the same. You could just have a shop redo only the roof. It’s on top where few people see. Good time to strip the rain gutter sealant and reseal too.I guess the thing that concerns me the most is the roof. I'm keeping that homemade wooden rack on right now, not so much for the cargo, but simply as a hat to keep the roof at least a little bit protected. But that rack is falling apart too. May have something to do with being plywood exposed to however many years of PNW temperate rainforest climate. Golly, I wonder why it's falling apart. Nevertheless, the one thing I don't want to do is to paint something for short term protection, in such a way that I just make a future high-quality job that much harder. Guess I have more reading to do, and Youtubing (is that a verb?)
