How do you get fiberglass out of a mold?
Furthermore, how do I make a fiberglass mold out of an existing part?

Besides, how many layers of fiberglass do you need for a mold?
For example, 9-10 layers of 1.5oz fiberglass mat will give you a mold thickness of around . 38" (which on a small mold is perfectly acceptable). On larger fiberglass molds, it may be more practical to add core materials to bring the mold up to the desired level of stiffness.
What does Fiberglass not stick to?
Fiberglass resins will not stick to woods that have been treated. They only stick to untreated, clean, dry wood. Redwood is not only usually treated, but it also contains a waxy substance prohibiting adhesion.
