I would like to know how you really feel.
I am using FRP-310 which is a water based adhesive. My test (slapping some on a piece of cement board, letting it dry for a few days, then laying under a gutter spout for a month, seems optimistic. It has retained adhesion to the board, and hasn't degraded in the sunlight. I'm not expecting to expose the interior to UV or excessive moisture. But you know leaks, like $#it, happen.
