I need to put together an entire post about my husband's rebuild of our pop=up TC roof. He totally dismantled and rebuilt it, finishing it up up with the Grizzly Grip truck bedliner in white. LOOKS INCREDIBLE!!! One little problem he is trying to figure out a way to fix...when he used adhesive to put the top layer of plywood down, it ate into the foam board insulation and now the roof has a little low place in it. He is kicking himself 5 ways to Sunday over it, but not about to start over. On the bright side...the water that was up there didn't leak into the camper!!!! The 4 coats he ended up with sure sealed it completely.
