I have to store my teardrop outside, not under cover other than a UV/water resistant cloth cover (but not a dropcloth!). Would fiberglassing the sides help? I think covering the whole thing (not just the roof) with aluminum would be best, but my husband wants wood sides -doesn't like the all aluminum look nearly as much. So I'm trying to find out what I can do to weatherproof the sides as best as possible. Perhaps marine grade epoxy/sealant, but I'm thinking fiberglass might be even better.
Doing a search didn't really answer my question.
