Release agent, Frekote Wolo

Hello to all, I have found Frekote Wolo semi permanent release, and I’m thinking whether to buy it.
I have found that it’s for polyester resin…my question is, it’s works also with epoxy resin? Can I use it with polyester mold, epoxy part, epoxy mold and epoxy part?

Do you think it works also with epoxy resin?
I saw that there is also the sealer, FMS sealer. Do you know where I can buy it? Small quantity, about a litre. I saw that is more expensive than wolo, and it makes no sense to take 5 litres
