Well, i have been using a Finex FX300, the HVLP gun. A while ago, i have posted a topic about too much orange peel, well, i started spraying my bodies flat instead of haning up and boy, it took care of 99% of the orange peel. Anyways, i considering i havent had any major problems with my gun, i dont think there should be any problems with another model, but then again, it is a differnt gun.
