I have a 2004 Rockwood 1640LTD pop up and i'm trying to figure out what material the outer roof is made out of. It seems like a thin fiberglass over possibly foam material, but not sure. I want to coat the roof to maintain a leakproof seal. It has never leaked, but it has bubbled up in a couple pretty good sized areas and that has caused some small cracking so I want to be sure no leaks form in the future.
Thanks in advance for any info you can give.
