Technically, how you fab CF is the same way you fab FG, you are just using different materials, and you have to consider the thread pattern with CF, unlike in FG (well there is a matt that's like CF for FG (silver and white), pero it's not used that often.)
CF - pros: very light but strong, considering it's not metal. con: expensive. Kung hindi mo ipang-kakarera sayang lang.
Fiberglass - pros: maraming gumagawa kaya medyo mura. con: porma lang talaga. Dagdag bigat lang 'to kung mga skirts, unless you go 100mph or more and aerodynamics come into play.
