Rubber roof loose

I'm in the process of applying bed liner to my roof and noticed the roof is loose in some areas. I'm planning to cut a small hole and inject some epoxy to re-glue it. Opinions?

    Does Grizzly Grip contain any hydrocarbon solvents? If so, that may be why you are seeing contraction of the EPDM. The solvents will react with a rubber roof.

    No idea, but whatever is has might interact with the rubber. The told me to wipe it down with acetone, which does interact with the rubber.

    Are you doing entire roof or just "painting" the seams?

    In one motorhome I did the whole roof (ACs off and everything).
    On the other just the seams and the roof over the cabover

    Depending on the size of the loose spot I would be more inclined to cut around the loose area on three sides, peel it back, and re-attach with contact cement.

    ps Let us know how the bed liner works out. Seems more people are going this route and I'm soon going to have to decide which way to go as well.


    The application was relatively easy, it is really strong and quite flexible. I'm using GrizzlyGrip white.
    The only issue is that it seems to shrink the rubber roof if not glued down.
