Will future damage your airbrush. I have read on a website that it can "ruin a good airbrush if not removed immediately".
In experimenting with my first future clear coat in prep for a wash, I had a hard time not spraying too much and creating puddles ( very upsetting). The stuff is so darn clear you can't see it till it's too late. This happens even with a 100 watt bulb sitting on my forehead ( i'm only 39.... I'm not goin' blind)!
Will I get better with experience. I don't have a regulator yet, so maybe my compressor is pumping to much PSI.
Still happy with the end results though. Blows away paintbrushing.

Shoot water with ammonia through the brush after use. Or if you want to get fancy, shoot the blue windshield washer fluid (98¢ a gallon at Wal-Mart) through it. Do not let Future dry in the brush.
