The previous owner trailer the RT a long ways on a open trailer, only to find the factory (read expensive) cover that unzipped at the antenna opening, flapping for hundreds of miles. The cover zipper did the following damage as shown by the white dots in the picture. Each dot is like a tiny crater with a raised rim. I dont want to get it repainted, and other solutions? I was wondering if some like Turtle Wax Black Box would work, but what about the tiny pit roughness?
