Hi all I just joined the forum and I recently, two weeks ago, bought a 2006 DTS in Philadelphia and drove home to Vermont, with no issues. The one owner car is in good overall condition with 72,000 miles. There are two body areas that need attention and cannot go unchecked here in the frozen north with the heavy use of salt and now brine on the roads. The bottom of the front passenger door is starting to bubble, will have to sandblast and paint. The passenger dog leg is my main concern, getting tender, the flange is rusted away, and will expose the rocker panels if untreated. I have searched the internet for repair panels with no success. Do I have to find a salvage yard and cut a used panel from a donor car?
