Early Corvettes weighted as much or more than a steel bodied car would have due to the required thickness of the FG.
I'm being very general in my estimations here, so flame suit on.

Nope, no one should flame you for your well stated comment. My point was the physics of the stuff, your's is the very nicely stated on how fiber glass is fabricated.
It comes down to the actual measurement of the weight of the panel in each material.
