Just get the hood painted to match the car...it won't cost that much. And what do you mean rust spots over the tires? You mean on the fender? If it's just surface rust, you'll need to sand that out and repaint it. If it's going through the metal and looks really bad, you'll need to grind it, put some Por15 on it, then patch it & paint it. It all depends on how bad it is.
