The reducer you add to the clear will control how fast the clear will dry depending on the room temperature, just make shure you get the right heat range in reducer for the temperature your going to spray in, I don't think that turbine sprayer will heat up much just spraying a playfield, or do I think hot air would have any effect on your painting results anyway. Are you spraying indoors or out? If you store your clear outside and its cold bring it in the house to warm up to room temp before spraying because when the clear is cold it does thicken causing the gun to clog when you spray it will orange peel beause it wont atomize enough before it lays down.
