Well, I did work in a pattern shop for over 15 years;you do pick up a few tricks. The wax I use is a custom formula that we used in the shop for patterns. It's a blend of 4 waxes with an orange pigment and talc(a filler). Believe it or not, we used oil paint for the pigment. I have a carefully hoarded supply from the good old days(Gahd I miss that job!). My "brilliant" articulated ankle is basically the same as the most recent 3 3/4" figure, though I did have to figure out a few engineering problems(such fun)...PS
