I just got an Iwata Eclipse. It is my first gun. Alls I got was the un. What other accessories do I need to get. What kind of paint can I use for automotive applications? Is there any good how tos out there for first timers? If this isnt a good gun tell me, I can retrn it and get a better one if needed. I just need a general use one that I can have fun with and use on my car. Thanks.
