Report Airbrush Hassles in General Modeling Posted May 2, 2011 I've had ongoing issues with my Pasche Dual Action airbrush for quite some time now. No matter how much I thin my paint, the airbrush does not spray. I have ensured the airbrish is clean and I have never let pain teven sit in the cup, let alone in the brush itself. I've replaced the needle, nozzle and several other parts and still nothing. The compressor also is good so I know it's not a pressure issue. Does anyone know what I might be missing here? I want to start building an aircraft kit but am on hold until I can get my airbrush woes figured out.
