Heat setting paint on wood?

[Ives]

I've just heard of this can't find anywhere how to do it. Except one super short Youtube video that mentions using a heat gun. I make little wooden figures and paint them with watercolours. Then sand, then coat with beeswax/olive oil polish. Still, if you wipe it with a wet cloth, some paint will come off, although it is stained into the wood so it won't entirely come off. But I'd like to stop paint coming off at all. They're toys, so they need to be 100% natural.

So, how are people heatsetting this???

That sounds a bit complicated. A clear spray acrylic lacquer such as this is what I use over my paints, although I'm sure you'll be able to find similar products more competitively priced elsewhere.
