I have done some minor stuff, but have never painted a whole car, although I do know the process. Im thinking about TRYING to paint my car. Can you get a decent paint job out of a cheapy gun like "Vaper" or "Titan"? I want to try silver, but im thinking that will be a difficult color choice for a first timer? Is silver considered to be hard to paint? I definitely want a light color to hide body work. Thanks!
