Oh boy is my shoulder sore today but it's clean except for the very, very top. After cleaning and conditioning the rubber roof, I just couldn't climb back up on top. I used RV Bug and Tar Cutter. It say's it's thick and stays where you spray it. Spray on, let sit a minute, then wipe off. Well, not exactly. It is thick but still drops a little. All the bugs did come off but with some I had to use a little elbow grease. I followed it all up by using Gel Gloss Wash and Wax. I love that stuff, just wash and rinse, no drying required and it dries to a beautiful finish.
