[QUOTE=jamesham;30174]Are you talking about the screws at the top where the roof meets the wall? There is usually a metal strip there, and sometimes an awning strip. We wrapped the edge with Eternabond roofing tape. This is very sticky stuff and once it is down, it holds well. Presume the Dicor product you mentioned is similar? The Eternabond tape has a peel-off plastic layer with a white vinyl outside layer. It also sticks well to fingers and your pants leg when trying to put the stuff on. But it stops leaks. We used it around all the skylights, on the front and back cap roof seams, and on the metal strip on both sides.

Yes, that metal strip that runs from the front cap to the rear end cap is held by screws and they will work themselves lose and poke holes through the Dicor. I bought the four inch rolls of Eternabond and just layed it right over the whole seam, just make sure it is clean. It can be washed real good with lacquer thinner, then apply the Eternabond. Also the seam in the front and rear that goes across, you have to apply the eternabond also.. But there are many other spots that need attention. Where the two radio antena's are mounted, the crank up TV antenna, the clearance lights, the spotlight, the vents, skylights. A leak could be on any of those spots. OH! also where your awning screws into the side walls. As much money as we pay for these vehicles it seems to me they could do a better job of having no leaks out of the factory. And it is just not Gulf Stream, I have talked to many other RVers with real high end coaches that have had leaks. Quality Control is just not there anymore like it used to be. But with a little time you can seal that coach to where you do not have to worry anymore with Eternabond and tighting the four bolts on the inside of your air conditioners/heat pumps.
