Hi all, New member here, used to airrush a lot but stopped for aw hile and now getting back into it. I'm having a problem with a Hader and Steenback Evolution airbrush that, when I press down on the trigger, I'm getting paint coming through before I pull back, which is anoying for fine detail work. I've cleaned the airbrush throughly and it worked fine for abotu five minutes but then started again. When I return the trigger forward and should only have air, I'm still getting a very thin stream of paint. I was advised to use light machine oil, but that only made the problem worse. I was also advised to clean the trigger and back end of the airbrush, which worked for a while but then the problem returned. It's happenign on a variety of paints: Molotov, Wicked and Aerocolour inks. Many thanks in advcne for any help offered! Paul.
