Fiberglass Hoods and Body Panels

I've had good luck with VFN's parts pretty much dropping into place, but I've only had the 3 hoods and one front bumper (also on the Dart) from them, the vintage road racing rules don't allow fiberglass fenders. The fiber glass racing apirn I bought for my'66 Mustang from Maier Racing 30 years ago WAS a bit if a nightmare to install...

I'm not so much looking to buy. I'm more interested in how they're made. Part of my focus for my bachelor's Senior project was composites and analyzing interlaminar stresses. Since I've never seen one in person, I was curious as to how different companies conduct their lay up and what material they use. I've seen a couple different ways of making a hood.
