Maybe I didn’t need a trailer in quite as rough shape… or at least I could have put stacks of solar inside vs. atop. On further Introspection and inspection, the bulk of damage was repeatedly ramming into an unseen tree as I tried to get off adjacent lot and onto my own. Whoops. Foam gun to the rescue; if I’m feeling fancy, I might even sand it and throw some Bondo on top. Paint? Maybe even with a paint sprayer?! Probably too much.
Plastics are great until they’re not. Sunlight’s ultraviolet seems to rapidly move most of them into the latter category. Bonus mask use: holding on the tail end of a motorcycle after its plastic succumbs to sunny bumps.
