i was thinking. what if u spread a nonstick substance like oil or something on part of the car and laid fiberglass on it to harden then u have a mold to use. then if u smooth out the inside of the fiberglass casting and painted some more non stick stuff on the casting and laid some fiberglass on top of that, then u would have a piece of fiberglass the same shape as the piece of metal that u cast fron and could make it as thick as u wanted. then u could cut out the chunk of metal that u cast from and fiberglass the sheet that u shaped to the body, cause then the car would weigh less. does this sound like an idea? has anyone attempted something like this? I made my own spoiler and it turned out pretty good.
