Rudy - UV is the problem - in my experience urethane glues are very good glues - if they aren't exposed to UV rays. Once it's exposed to UV it starts to break down. Same thing goes for that inject-able foam insulation - any part of it exposed to sunlight crumbles in short order. I'm a West fan myself been using it for years.

Really helpful. Yeah, I would stick to WEST system or the other leading epoxy for marine applications.
