I am in the process of installing a Winegard satellite / over air antenna on our 2009 Big Country. I have removed the factory antenna and cleaned all the sealer away, and my question is what sealers / glues are used by Heartland on the roof, or if anyone else has a suggestion of what to seal it to the rubber roof with. By the look of what came off, I think it was glued down first with a construction adhesive, looked like PL100 or something, and then a white sealer "poured" over the screw holes and outline of unit. Any input greatly appreciated.
