I was trying to find out what certain body kits were made of, Here's what I found. Hope this helps. Body Kit Material List
Air Force 1- Fiberglass
Bomex - Fiberglass
Veilside - Fiberglass
After I read a couple threads, I was moved to share some knowledge. This is not directed at any competitors or a certain company. You can do your own research and ask questions from whatever vendor you are interested in buying from.
There is nothing wrong with fiberglass if it is hand laid...
