I once needed to make some fiberglass hemispheres. I found a lightbulb the
right size, sprayed some WD-40 on it, layed up some fiberglass and it
realeased
nicely. I then used the fiberglass form to make several hemispheres using
WD-40 as a release agent.

I have a friend that uses the cooking spray PAM as a mold release. I've
never tried it but it works for him.
