I've got a pretty bad roof rust problem, and I'm trying to get together a game plan to tackle it right and paint the whole vehicle this summer. As you can see there have been multiple attempts to fix it before 4+ and counting! I would like to remove the whole upper rack assembly and bumpers, sand down to bare metal, and paint with something rust resistant. Then move onto painting the whole vehicle. I have to idea how to remove the rack/bumpers, they look like they're riveted in place, but I cant figure out how they would be reinstalled. Has anyone done this, or have any advice for prime/paint products that have worked well in the past?
