I'm making a fiberglass mold and want to apply something to the wood first that the fiberglass won't stick to. As thin of a material as possible preferably.

Any help would be great.

Yea. I saw that too. Only problem is that it's thick. Especially where it overlaps. Any other ideas?

mold release wax is available from fiberglass shops this should fix you up! Rub it on and fiberglass over it! When the glass is dried give it a solid wack with a rubber mallet and it will let go!

First use mold release wax then PVA, they should both be available from a reputable fiberglass supplier.

I also like to use a cheescloth to the PVA, I tried using a brush but you get those "brush marks" in my parts. And I am too lazy to spray it.
