I bought a 2007 diplomat and have been slowly working the bugs out. I am starting on the roof, but the p/o has done some repairs(?) and I am not sure of how the factory sealed the roof. The caps have some type of foil tape, butyl, dicor, silicone, and some type of mastic brushed over all of it. It is a mess. Does anyone have a picture of their cap joints from the factory? What about the curbside awning mount?
