The poly glues like Gorilla or ProBond are the best thing on the planet for working with foam. I use quite a bit of it. Like Flyboy, I have piles of different glues and differnet types of glues for differnet uses.

Another great glue that many folks don't know about is Goop. It's great on anything plastic, like cowls and windscreens, and coro. Also works great on woods.
