OK, when we camp, my husband backs up the truck, and I line him up and lower the power hitch onto the ball. Usually works well. This time, for some reason, he leaned the stabilizer bars up against the front wall of the trailer vertically instead of having them lying on the ground. I didn't notice. So, as I lowered the trailer onto the ball, suddenly I heard "pop"! The stabilizer bar poked right thru the silver part of the trailer that looks like aluminum with all the criss crosses (but is actually some sort of plastic). Didn't go all the way through to the storage compartment, but it's a hole about 2-3 inches in diameter! I could see what appears to be insulation inside. I used a coat hanger to pry the plastic back into place, but there's still space for water, bugs, etc to get in
What can we use to patch that?? For now, there's clear packing tape over it. We were thinking maybe a spray sealant?
