Take a look at West Systems - G/Flex Epoxy. A 2 part glue.

Reasonable price for 8 oz, Slow setup (45 mins for initial working time) but glues many different kinds of materials. Woods, Plastics, Foams & moreI just bought a kit & think it will be useful, very strong & versatile. Formulated to withstand the stresses of expansion, contraction, vibration & Impact. So it says on the label anyway.

Those folks are big in Marine adhesives that I know of. I expect it will be good stuff.
