"Fiberglass" is made from glass fibers and plastic (resin).
You can make it very lightweight by making it very thin, there is fiberglass cloth that is very thin, like rice paper,
Surfacing Veil Mat • Ultrathin: TAP Plastics
But won't have much strength, sandwiched with foam, it might be strong enough to keep its shape, but a rock would probably dig a hole into it.

i already have a billit grill, which probably helps block air, and looks awsome, but has an annoying resonance at 50-60mph.
i always thought fiberglass was heavy and expensive when compared to plastic.
