You can use the Fuji Touch-Up Turbine Spray Gun any Fuji HVLP turbine. Just attach the quick-connect coupler to your hose and begin spraying. The Touch-Up gun comes with a 225ml capacity cup. It has a 1.0mm stainless steel needle, nozzle and aluminium aircap. The spray pattern is adjustable from round 6mm to 150mm. This spray gun is really handy for projects that require smaller touch-up work. The smaller size makes it ideal for hard-to-reach places, when your standard gun is too large.
