I'd recommend fiberglass cloth (6 oz) in epoxy. If you lay it on the bias it will form a compound curve easily (in other words, it stretches very easily on the diagonal). Epoxy works very well with styrofoam, unlike polyester resin. Also If you are doing this at home, it doesn't stink up the whole house the way polyester resin does.
The nose on the Zing! was made like this. After the fiberglass is on, then you can use bondo to fill in any little dings from sanding the foam.
The disadvantage to epoxy is a longer cure time, and higher cost.
