Well i found this link on how to fiberglass boxes and stuff. excellent write up on how to fiberglass boxes and stuff. Well here it is http://web.njit.edu/~cas1383/proj/main/ hopefully it'll help someone out that wanted to do this or just wanted more info on it, i know i'm going to try to fiberglass something after reading it.

good luck, it's pretty expensive and way harder than it may sound. Took me over 5 tries to get my box decent in my old car.
