Be careful using Westley's Bleech-White near the rubber roof and also near the vinyl inserts in the corner moldings. It will make the roof EPDM tacky and possibly damage it as well as turn the white vinyl insert to a off white/yellow in only a couple of applications. As for the Filon or fiberglass, I'm not sure what it does to the coating, but you're right, it does make the bugs fall away.
