Airbrush

[jpw]

Hello all been trying airbrushing for a while now started with a neo airbrush and had nothing but problems, replaced needle guide etc but have never really been able to get it to work always splattered and seems to have back pressure going into paint cup ,tried cleaning and thinning. Although it dose work better when I remove the protector cap from the end. So after than I decided in my wisdom to try a cheap brush from eBay and things have only gone worse is buying cheap a recipe for failure what the airbrush of choose.
