Better Than Eternabond Roofing and RV black Rubber Repair Tape 4" x 50'

I removed all the old caulking material with a wire wheel, the old termination bars, and any Eternabond that was down in the first place. Relatively speaking, I really started out with a fresh surface. I then primed everywhere I put this tape with Dicor Primer. It sticks like crazy after the primer. Make sure you get it where you want it or you will not be able to remove it and then put it down again. After placing new termination bars, replacing any fixtures, and sealing all edges of the roof and the fixtures on the roof with this tape, I then went over everything with primer again...the whole surface of the roof. At this point I painted over the whole roof with liquid EPDM roofing rubber. Beautiful surface has been through many downpours, and I mean rain of several inches at one time, and not leaked one drop. Best bet is my motorhome roof will never again have a leak. Prep is the key.
