Painting the Dart

Looks like you've got some rust issues to address in those rear quarters. If you paint over that, it'll be coming through before you know it, it won't take long. Then you'll just have another coat of paint to deal with and have to do it all over anyways. IMO, not money well spent.
Yes there’s a couple small areas. The worst is a softball size hole on the underside of the rear quarter. Other than that just some surface rust. I plan on cleaning that up but was wondering if I needed to remove all of the other paint before respraying or if that’s already a good base?
