Anything I should know? I've done some research in spraying and 1.4 mm tip is probably the best route to go for me. I got a hvlp gravity fed gun too. I guess what i am wondering IS THERE ANYTHING I NEED TO WATCH OUT FOR WHEN PAINTING MY WHOLE WITH THIS GUN? i am aware of the needed air pressure as well so you can leave that part out as well. Im lost on WHAT TYPE OF PAINT TO BUY?? and CAN I PAINT THE CAR IN SECTIONS? LIKE TAKE OFF THE DOOR AND PAINT THAT SEPERATE?? what are the negative sides to painting seperate items?
