my friends making a fiberglass hood and i'm helping him so heres what we're doing.
first we used his old hood, and sprayed PVA on it, pva is a sort of plastic dissolved in alcohol so basically you spray it and it turns into a very thin sheet of plastic. like a very cheap plastic bag.
after you do that and it dries, then you stick a gel that hardens to get all the detail and then after that, you lay fiberglass and resin in layers etc after you think its solid enough. you either rip the fiberglass off from the hood or invent some sort of brace for the fiberglass so it holds its shape. ie that expanding foam + chicken wire etc.. you can pop the hood off from the fiberglass becuase you used the pva which allows for sepearation. its easier to tear a plastic bag then resin bonded to metal. after you've ripped off the fiberglass. then that your mold and you make sure its all good and prep it and then you do the whole process again in reverse to make the actual hood.
those instructions were for a hood but i'm sure you can think about them and probably do it for just about any other part on your car and substitute materials appropriately.
good luck
sounds like some helpful tips. where can you get this PVA stuff? Walmart? local hardware shop?
