How I repaired my damaged section of my fiberglass wall

Nice job! When I re-did the truck camper, I took off the rest of the side and replaced the whole wall (actually 3 of them) but your trailer would need a LOT more filon. I attached the luann first then sprayed the adhesive on, laminated the fiberglas in place, then trimmed the excess with a router.

Here's my Lance build, summer covid project.
