Mold release agent

I'm getting started on my fiberglass Clone armor. I have a mold ready, but I need a release agent. I'll pick up some Vasoline, because I her it works well. But would WD-40 also work?

Vaseline mixed with mineral spirits makes a good release agent. Also, silicon spray works well...

i was gonna say that i used silicone spray with great results before

does vaseline alone work well as a release agent for fiberglass?

believe it or not, i heard Cooking spray works well.. I havnt personally tried it, but a buck a can at the store.. I might try on something soon.
