Without fiberglass, the foam might be strong enough with resin; without resin, definitely not. It punctures quite easily, which a vinyl wrap wouldn't really protect against.

With two layers of fiberglass, 1/2" foamboard is as strong as 1/4" aluminum sheet, according to an engineer I talked with yesterday (who is building a 240-mph motorcycle streamliner to take to Bonneville and skinning it with foam/fiberglass--it's quite a sight, but with no body yet).
