Thanks for all the good advice and tips HOTRODPAINT and SprayTec.
I wash the air brushes out with wot water a couple days ago and they came out spotless. I tried to wash them out with thinner yesterday and not so good.
But now we know,nothing like a little trial and error. Jello explains it very well.
I did spray it thru though and they seem to be working good.
From now on it will be hot water for the water base stuff.
I did 4 shirts for my brother in laws kid and they came out good.
But I can see that I need a better air brush for the real fine work.
There is a big differance from painting on shirt and cars though.
The shirt absorbs any extra paint and on the car body the extra paint tries to run.
But it's all about practice and learning to control the airbrush trigger just right.
Thanks again for all your help. Kurt
