If the car has an aftermarket paint job, then YES by all means do this, but with the stock paint job you will sand through the clear coat and cause paint failure. Shops won't touch your car with a wetsand unless you have a few extra coats of clear to spare. Ford, as well as just about 90% of other car manufacturers, do not put enough coats of clear on your car to do this efficiently.That's right. The only thing you can do now is try to make the damage less noticeable by lightly wet sanding the area with 2500-3000 grit then buff it. That will help, but no full fix.
