Heat Source

I'm with Skip on this one, except I use one of the butane burners that use the disposable butane bottles. Fast and cheap.

i pour my heads and only paint as many as i need. i paint more as i need more. when i need more i take my heat gun and heat the jighead for about 5-7 seconds then dip into powder paint , then heat with the heat gun again for about 7 seconds. hang on a rack till they cool and they are ready to use. it is simple and it works for me.
