1. No idea about the priming.Originally Posted by roknee link=1196040183/0#0 date=1196040183
2. Or pre-infusion.
3. ALOT? I think its two words. "A great deal", "A little", and so, "A lot".
4. Keep doing it til you get callouses. *;) Seriously, I use the inside of my pointer finger (umm, the side of it, where it sits next to my middle finger), and the heat usually doesnt bother me anymore.
Im sure someone else will be able to help you with your other questions.
