Glow in the dark pigment help

[thehive]

So I just recieved some pigment from king of sneakers. I mixed the pigment with 2 thin to use in my airbrush (what they recommend) I'm having a horrible time trying to get a good spray. I have to filter it or else it clogs my Airbrush. They don't say how much 2 thin to add to the powder. Any one else done something similar ?
