No additional UV protection is required. Do you have any manufacturers for the stick on armor? I have a couple applications for something like that in other areas.
Andreas, where'd your post go? That was good info on repairing delamination. I've fixed a few delams on other manufacturers products, some were easy on the better stuff, the lower end RV stuff was a pain. The lower end stuff was really thin frp bonded to luan bonded to foam bonded to more junk, typical RV stuff. The issue was the luan was either rotten or was basically coming apart, and you just can't get that decomposition factor out of the wall, and in that respect the rest of the wall is generally not far off of the condition that the failed section was.
Swirvin, there is a medic body designed and manufactured in Canada using an extrusion that isn't as structural, and the same panels. They have passed CMVSS (our version of FMVSS, basically a copy) for static roof crush and passed with flying colors, and seeing a few units that were in roll overs and collisions and held up exceptionally well. I'd say a minor collision that would write off a conventional unit would not affect a composite unit anywhere near that degree. There were a couple pics of a Mog that landed on it's side a few years ago posted up on this site, the shell was great, the truck cab was not as good.
