Super Chief, An FG cowl is a cowl made from fiberglass. There are many threads on making molds and using fiberglass, so I won't bore you with the details here. Sorry I didn't take pictures of the process 'cause I keep getting asked about. Just do a search for making fiberglass cowls, here or try utube for a video. Fiberglassing is a really useful tool to know in this hobby. Thanks for the compliment on mine.
