The wax helps protect the stain, and also helps keep the skull (particularly the teeth) from drying out. Until I got into doing this stuff, I thought bone was completely stable. Kept out of strong heat and direct sunlight, it is very stable, but not perfectly.
I put on enough to cover the surface well (mostly by hand but I have old toothbrushes and some shaver-cleaning brushes for hard to reach areas), let it sit for a while, and then buff it with a cotton rag. On porous bone (or wood, etc.) I hand-rub briskly to heat the wax and drive it into the pores (or use a hair dryer, carefully) and may repeat the coating and rubbing several times.
All of them, though how porous varies. The outsides of teeth are pretty solid. Mostly the porosity is very tiny, even microscopic, not like a sponge. More like wood.
I could look it up, but you're a reliable source.
How do you apply it?
What sort of bones are porous?

Right, right. Interesting. Thanks for answering all the questions!
