If you do have rust and want to wait to replace the panel, use a phosphoric acid type rust remover. There are alot of them on the market. The one I use is OsPho. Be careful, wear gloves and put cardboard down on the driveway cause it'll eat concrete too. Keep that young man in your avatar from playin around the area. Rinse(dilute) spills with water. Clean up the white residue with a wire brush before painting. Permatex makes another rust treatment who's name escapes me, but its more civilized and goes on white and turns black after it dries. It works good, slowing most rust areas down from decay considerably. Thats my experience with rust. Hope it helps. <img src="/forums/images/graemlins/notooth.gif" alt="" />
