If it's clearcoated it must be a repaint. Some body shops will do this just because it's less work. Generally clear coat has to go one right away, can be a problem if you wait too long - but the main rule is follow the manufacturer's / dealer's directions. I doubt if you're going to have a fading problem - it's not that noticeable a panel. If you do you might be able to blend it around the corner. As mentioned I think you are better to go thin. If you go thick with air dryed paint on the front of the car like that you will have a half dozen rock chips on both sides within a year, assuming you do some highway driving. It won't even take a rock to chip it - a hardheaded bug will do.
