Hi to everyone here,my first post. My question is about corrosion under the clear coat on various areas of our coach. The two battery boxes up front,is there a way to get the approx. 1 inch trim off to deal with corroded parts. My door hinges are also bad but I have new ones to replace those. Looks like replacing hinges is another headache but solvable. My tail lights is another story but won't get into that here right now. Only need advice with outside battery box trim. Thanks to all responding. By the way our AS is a 2003 31 ft. Classic.
