I recently purchased an aluminum hardtop of which I was informed that only 300 were made. The removable portion of the top is dented fairly severely. There was, is, a thin coating of “bondo” left on the top which was used as a leveling course. Question?? I need to restore to a fair level of usefulness and it must look respectable. How might I proceed??? Thanks Stew K P.S. The aluminum is quite thin and the headliner is gone although they can be obtained or custom made.
