Yup, heat gun is the only way to do it, got mine at Wal-mart for like 20 or 25 bucks, 2 heat settings. Low is all you need.
Have done heads down to 1/80 oz. with no trouble. But have seen times if you do a white base, then a darker color on top, then bake the head, the darker color will fade. So any more, i just do the base color, then bake, then reheat the head with the heat gun, and apply second color, darker color comes out fine, and i dont have to re-bake.
Painting heads like this, is as bad as jig tying, ITS ADDICTING !!
THANKS, cadman for the idea.
