The stuff I worked with was not closed cell (greatstuff) and it soaked water up like a sponge. My project almost sank. I ended up sealing all the open pores with epoxy. You can find Nichrome wire at Mcmaster.com. Watch out for spray insulation.

Oh how much frustration I've had trying to shape polystyrene foam. Best to cut it with nichrome wire. Oh, that should be Liquid Nails. Ive used Klegecell on a big boat project a few years ago. That's some nice stuff to work with (Very $$! though). Urethane foam is a lot more brittle. Look forward to seeing it progress. How's the Arduino working out. I'd like to see you doing something cool with that. True.

That's why I think I'll need to give it a thick coat of paint before glassing it if I don't switch. I'm going to put a few more panels on and then decide -- they just cost me $6 so it's not a big loss other than some time if I change my mind.

Not reactive with polystyrene foam. I'm a bit concerned with using polystyrene foam. As I recall, it doesn't play well with polyester resin. Maybe epoxy is ok. From a structural standpoint, I think it would be advantagious to use a urethane foam that the resin will bond to. by painting it, I think you'll lose some structural properties.
