I'm thinking about having that plastic coating sprayed on mine. I will probably get one ot the vinyl bras like Truk now has to protect the plastic coating. If I start worrying about the vinyl getting messed up, I will install the plastic shield like Denny and Jim K. have on theirs.
Actually, if I had taken any of the three precautionary measures, I might not have those twin dents that I currently sport on the front of my bus. The previous owner had used the plastic shield, but he removed it when it became cloudy and was not able to locate it when I bought the bus.
