Hi chap i've used allot of diffrent paint as allot of other people on here have.
The 1 question i would ask is, what marker are you using? As the tippmans need harder paint in winter due to the cyclone system.
if your using a space gun as the woodball players call them then tbh i love proto and i have a case upstair waiting for my next game.
Just keep em warm with either a flametek bag or charcoal hand warmer while at the event as there not winter paint.
