Check locally for a fiberglass materials provider. If they are a well-established and experienced business, they can tell you exactly what you need, and how to use it.

Good old Johnson's Paste Wax is an excellent mold release for fiberglass mold making. I was taught to wax the surface thoroughly, five times. Spray on gel-coat, then lay up enough glass to be rigid. For a one off, 3-4 layers of 1 1/2 oz matt should be enough. A production mold should be much thicker. And it would need extra bracing.

Using this method yields an exact reverse copy of the surface. I tested it once on a door window. The brand and identification etching was perfectly visible in the gel-coat when it was removed.

If you're afraid of trusting just the wax, you can mist on a coat of PVA- Poly-Vinyl-Alcohol. PVA is a water soluable release agent.

This process can be done without gel-coat, by using straight resin. I think the gel-coat is worth the trouble.

I used to manufacture Corvette parts using Feather-Fil as the gel-coat. That made it easier to block sand before painting.
