Tempilstiks and Thermomelt are 2 brands you might find, When the stick melts, the precise temperature is reached, so they may be a bit fiddely in this aplication. I'm yet to see the paint on stuff but it sounds more practicle for this.
To properly anneal brass, the temperature needs to be at 650 degrees F
I rotate mine in a small deep socket ( about a 1/2 " - 1/4 drive ) in the cordless drill at low speed with the neck and shoulder sticking out, in a dark room and hold the flame ( i use a LPG torch ) on them untill I can see a very faint glow then dunk them into a deep bucket of water to prevent the heat soaking into the rest of the case.
Also the small electric lead melting pots for bullet casting hold the perfict tempture for annealing brass, just dip the neck in up to where you want it annealed and give it 10 to 15 seconds.
Gun control requires concentration and a steady hand
