I have a spare driver's side door that has a little surface rust, mostly on the interior side, and some rust bleeeding around the seams where the outer skin is folded around the door. The rust issues come from the door being stored in a barn lean-to with one side open to the elements. From a quick observation, this is all surface rust, no rust through issues are apparent, but I am concerned with what cannot be seen. I had thought about having the door commercially chemically stripped, but am concerned about chemical leaching in and around the seams. What is the preferred method of treatment in this situation? I would appreciate the advice of restorers who have had to deal with this situation. Thanks.
