There is alot of good info. on this subject but one thing is left out about water. Tap water has minerals in it where as distilled or soft water does'nt and it will make a difference as a reducer. A detail gun with a 1.2mm fluid tip will do a great job with properly thinned laytex with flotrol. What ever you do don't let any of it dry in your gun because it will really gum it up. That same gun is perfect for applying the clear coat. I'm surprised someone could spray it with a air brush.

Some nice paint jobs shown here fellas, very nice. Leroy
