My guess is that, somehow the wood or glass got contaminated and ruined the bond. Another possibility might be a high moisture content in the wood while glassing and then the wood outgassed the moisture in the hot sun. I have also been told, by Jo Greenley, that some epoxies don't hold up as well in the heat as well as others do. He said that MAS does better in the heat than System Three. What kind of epoxy are you using.
