I'm having trouble spraying fine lines and details. As I understand it, to spray fine lines you have to spray a small amount of paint and have your airbrush close to your work. Within a 1/2 or even 1/4 of an inch. When I do this with the air pressure set at 35 to 40 psi it splatters paint and pushes it everywhere in a star pattern. I've tried reducing the air pressure to 20 or 25 psi, but when I do this the paint doesn't want to pick up through the syphon feed. Do I need to be using a gravity feed to make these details? If it makes a difference, I'm using a Paasche VL dual action airbrush. thanks, RayburnGuy
