Hello everyone, I am having trouble with my airbrush. I have H&S evolution. I am using 2.5 pressure and my needle is good inside is clean I am unable to make a straight line it always splashes around ( little paint droplets around it). what can be the cause. I was thinking about consistency of the paint. but I believe it is good . What can be the problem? The picture I uploaded, has a little bit more thinner. thank you !
