Nice gun, to big a nozzle though, a 2.0 is for heavier bodied primers, shoot for a 1.4 tip for urethane base and clear, if you are just shooting a engine, throw 50-100 ft of air hose outsde run a length back inside and run a cheap water trap inside then a last chance filter in the gun, you will be fine, that section will give the air a chance to cool down and condensation will then separate upon the air getting a chance to cool down with the long run. Save your money on a dryer till you paint a whole car and take the wife out to dinner, if that's all your spraying you'll be fine
