Aluminum roof maintenance/repair
I just purchased a 1989 Winnebago Warrior 22'. I've owned newer trailers for many years, but this is my first coach and it has an bare aluminum roof. The aluminum looks in good shape and I know I need to perform maintenance around all the the openings in the roof and I'd like to maintain the joint between the aluminum roof and the fiberglass crown area between the roof and the exterior walls.
What products would you recommend for this? I see lots of people use Kool Seal and a local RV dealer stocks the Dyco 890. I'm looking to seal the openings, protect and seal the joint and protect the bare aluminum.
