How-to coat insulation foam to make it stronger?

Ok, this isn't a how-to, but it's a how-to quetion that hopefully will help other people out once I get an answer.

I bought a HUGE piece of pink insulation foam the other day to start making aeromods for my car. However, it has one downfall. When using it to make a large surface, it's flexes...A LOT and that might ultimately lead to it breaking. It seems to work fine as a grill block material since there is structural re-enforcement behind it from the bumper pieces, but I want to make wheel skirts out of it and I'm concerned that making it as such a large piece with little, or no, support except on the edges, it might just break. Is there some kind of stuff I can spray on it, or coat it with to make it have sort of a plastic like shell on the outside? That might give it just enough structural re-enforcement that it won't snap with the wind hitting it and also might be able to give it a smoother shell so the paint looks better on it as well.
