If you've got more than a scratch or two on your car, you're well beyond the point of being able to use a touch-up pen or something similar; you need to spray it. The problem is that an airbrush is expensive, and spray-paint looks terrible. What is one to do?
MacGuyver a man-powered airbrush like this guy. He's brilliant as long as he doesn't accidentally inhale.
