One good answer now is PVC-KLEGICELL, stronger, shear is 100 times greater than green or tan urethane.
Actually the original styrofoam used in Eze's was white, a lot of the Q2's had orange, blue came later.

One is polystyrene, and fuel will dissolve it quickly. I believe there is another type that will not, but it's more of an open cell stuff, maybe urethane, so you're right back where we started. I have a small leak on my "main" (passenger) tank. If I fill it up to within about 1.5" of the top, I can smell fuel in the plane later. Needless to say, I don't fill it to within 2" any more, but if I had styrofoam wing skins, they'd have been flapping in the breeze a long time ago. and I'm pretty sure that tank would have no bottom in it now...
