When putting my roof rack on today, I noticed a few small chips on the roof that have started to rust out. I figure I'll use an abrasive buff or flapwheel on my Dremel to clean the chips down to bare metal and then use some touchup paint on them. I've never done a touchup job though.
Can someone point me to a good place to get paint and/or a kit? I'm happy with doing 2-3 coats, sanding and polishing in between to smooth it out. It doesn't need to look amazing (they are on the roof after all), I really care more about it lasting and not rusting out.
Suggestions? Thanks!
