Hi everybody, I have a 2003 dutchment class c RV. and before we put the tarp on it last fall we noticed that we had a water leak above the cab of the rv. I am trying to find a caulking that will work on the seams of the fiberglass and where the roof meets the seams of the fiberglass. I have read on a few other posts that OSI Quad caulk at home depot or lowes would work. What do you think. I am leaving for vacation in two weeks and have no local rv stores. So, I am trying to find a caulk at local store.
P.S. There is no ac around me otherwise I would get proflex.
