Probably OK for making a "grille plug", but not so good for wheel skirts, which need to have some structural strength and can only be so thick.

I could however see using this kind of stuff to build & shape the skirt area, apply a release agent and skin it with fiberglass - you end up with light, stiff skirts by making a polyurethane mold to lay the glass on.
