Very nice car
the silver fiber is fiberglass that has been thru an aluminization process.. it's trade name is Texalium, but a few companies make the cloth. It is sometimes a pain to work with, it is harder to lay up than carbon fiber because the material is stiff from being coated with aluminum. Carbon fiber is always black.. so If you see colored "carbon fiber" the color is applied to kevlar, fiberglass, polyester, or PET and then woven on a loom along with carbon fiber.. this is how they make black/color composite cloths.
just a little inside info
