Seems everytime i ask for or look for practical info on fiberglass i usually just come up with a whole bunch of nonsense, non-answers, and overly technical discussion. even the books i've bought are kinda useless for putting into practical use. I get how fiberglass works and the process to make parts and such, but what i cant find is guidelines for how much of what type of material to do different jobs. even the supply house has no answers. Like: how much of what to make a t bucket body as opposed to a funny car body as opposed to a hood scoop as opposed to repairing a crack or filling a hole. SOMEBODY out in HAMB land has to be able to help out if not by directing me to some super secret fiberglass forum that i haven't been able to find. PLEASE!!! I have a garage full of stuff i'd like to get cracking on, but i'm just kinda lost.
this one has some numbers...but you'll probably have to figure out how thick you want to make the parts. Probably from 1/16" for the thinnest, non structural parts, to 1/4" for heavy stuff, and most will be between 1/16" and 1/8" http://www.tapplastics.com/uploads/pdf/Laminate Guide.pdf
As Jim says, you need to know how thick you need the parts to be and also the surface area so that you can come up with a materials list. On some parts you may need to bulk up in high load areas (mounting flanges etc) while leaving the rest a little thinner. If you are going to build race car stuff cloth is better than mat. Also if you are trying to keep things light and the part is going to be painted, use just enough gel coat to keep the cloth/mat from sticking out of the surface. Roo

Hey Mitch. I been doing fiberglass/gel coat repair for a living for the past 17 years. All marine application but I may be able to save you from a few headaches. let me know.
Hey you guys, please keep it on the forum. I would be one to follow along. Never can have too much knowledge. I've done a bit of glass work in the past, but would like to see the tips and tricks you might have.
I was going to suggest checking out some of the marine fiberglass books. Jay can probably walk you through a lot of it though. I had to do a lot of reading up on it and then apply what I learned on my sailboat after I bought it and eliminated a lot of through hull fittings.
