Most epoxies create heat of some degree, through chemical reaction to each other.

And how much hardener you add.[emoji38]

I would worry that the thin layer of wax, wouldn't hold up under the heat, or possibly the chemicals that make up the epoxy, would eat it away.

Just a curious, measure twice, cut once, KISS, kinda guy. [emoji57]

I've only used it with relatively thin layups of epoxy/glass, polyester/glass, and on the epoxy/paper micarta that I make, so heat has not been an issue. I'ts a bit scary the first time you rely on it with a mold that you have a lot of work in, but I've never had any problems. As I said there are waxes made specifically as mold releases. I use 'Part All' because I have it. If I were going to use other waxes in a 'must work' situation, a test prior to use would be prudent.
