RV FlexArmor is another.
The difference between this and a truck bed lining is that these stretch and bend, while just a plain bedliner would crack, and cause gaps that water can intrude in.
I really want to see some place in central TX that offers either of these, just because it would give peace of mind, and make the 90 day roof checkup just a quick look for obvious cracks, as opposed to having to get the Dicor tubes and scraper. I'd even have this done over a fiberglass roof just so that areas normally sealed by caulk are completely covered over.
