Fresh paint can burn real easily so you have to go easy and really watch the edges. When you buff close to edges you want the wheel spinning off the panel not into the edge if that makes sense. Real tight areas run a piece of tape down the edge.
Will keep that in mind. Using Porter Cable 6" random orbit, I used it on the Magnum and think I could have camped out on the edges. Don't think I ever came close to cutting through.
