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.

Fiberglass and steel expand at different rates. Sooner or later the seam where your panels are joined are going to crack. Could make a buck for shaping a steel panel this way though.

I agree. Some have been successful bonding fiberglass to steel using a special epoxy but only as a full panel overlay, or where there are borders and seams. Also most autobody supply stores can get special mold release waxes and spray on mold release products that wont harm resins. In a pinch, I've used several buffed coats of Johnsons past floor wax, then cleaned the part with a wax & grease remover.

thanks for the info guys i guess it wouldnt be that great of an idea after all then? and that spray on mold stuff, got any links to sites or idea of cost cause that souds like good stuff but it could be expensive and not really worth it.

thanks Old Newby:
that mold making kit is cheaper than i though it would be.

My rear quarters were severly rusted out we used that spray foam filled in the holes,then smoothed it out ,and finally layed fiberglass over it.So far it's holding up pretty good may do the same thing with the roof which is rusted very bad.

It's been holding for a couple of years now it still looks pretty good.It'll probably need to gone over to freshen up here soon but it looks fine i'm likely going to do the same with the roof.

thats been holding up for a while, glad to her it...sounds like your car will be made of fiberglass in a few years should be good for your ET's...

Yeah i'm thinking of putting on a fiberglass hood.Probably gonna glass every area that has rust it seems to be alot less work.
