Fiberglass 101

[77SceptreOB]

I'm thinking of making some fiberglass parts. First I'm going to make a mold.

After I make the mold, what type of material (Clay) should I use to form / mold the corners to be smooth?

What type of wax should I use to keep the fiberglass & resin from "sticking" to mold?

Any other critical info I should know??

I'm going to practice a few times before the real parts go in the finished mold.

Polyester resin, right?
