I want to learn how to make car body's out of mold?

I want to learn how kit car body's are made for the classic Ford GT40's and other classic cars kit cars, what is a great learns guide for this or building car body's in general.

You-Tube is your friend. Moulding fibreglass is "easy" but the quality of the mould is what will make or break the finished product.

MOLD is a fungus that grows on plants and shower walls. It is sometimes toxic. One DOES NOT make car bodies "out of mold."

If you want to build car bodies from A mold, you MIGHT be able to do that, but you need to learn how to work with fiberglass and plastic resins. Probably a lot more information required than just a question on an Internet Q&A forum.

Maybe you should go visit your school's library and look for BOOKS on the subject. READ THEM!
