[Spridgets] Fiberglass question

I need some kind of mold release agent, PVA would do nicely but I'm having
trouble finding any I can go and buy today.
I can order from an online place, but that's not going to get the job done
I have a plaster cast mold I want to lay in some fiberglass and resin and
then be able to pop it out without breaking the mold.
In a previous job I had doing this kind of thing (several decades ago) we
would use special chemicals and everything worked great.
Now I want to do a little of this at home in my spare time, making
impossible to buy new spridget bits & pieces out of fiberglass.
Anyone think of a substitute for PVA or some other way of doing this?
For the casting metal piece that I was putting into the plaster to create
the mold I rubbed the surface all over with wax from a candle.
It popped right out perfectly.
I'm considering giving the mold the same treatment, then laying in the
fiberglass and resin and then just hope it comes out cleanly.
Any other ideas?
