So mine has the usual corrosion at the bottom. I had it painted in May, and the painter said that it was buggered and the corrosion would come through in no time. Well it has. I stuck rubber trim a long the bottom, but that did not work well, so I removed that but now have glue and silicone all along the bottom of the tailgate. I probably will sand the bottom down, smooth it. I have found (tested) that a strip of duct tape along the bottom looks tidy (ish). I would buy a replacement tailgate but they all have corrosion! Any tips?
