I recently purchased a used RV with painted aluminum siding. The corrugated stuff. It has some dull spots in the finish where it appears the previous owner sprayed it with something (trying to clean it??). I have tried wahing and using a cleaner wax with no luck to restore the dull, hazy spots to the shine of the rest of the camper. Any suggestions on what I can do to get these spots back to the original shine of the finish??
