A company in Sarasota? Florida called "Fiberglass Coatings" has a pretty
good free (I think) manual on this subject. They also sell materials
pretty inexpensively. I've ordered from them twice and had good luck.
Here is the address of their website. http://www.fgci.com
Go to the "how to" section. I think the hardcopy catalogue/manual goes
into more depth than the web site.
This source may be too simplified for you but I think they also sell
books on the subject.
Good luck
