Slickback

I think the main issue with rust is that when these cars were built, they never took the time to prep and seal the surface properly. As well, years of sun damage etc. allowed for the crap, salt and moisture to get in. If you paint the roof, and simply scuff before reinstallation, and like most people are doing now, avoid driving in the middle of salty winters, I think it's a non-issue.
