In the first pic you see the blue going into the black. That mistake is only about a half inch. It was clear coated. What's the best option to fix it ? Scuff, then respray ? In the second pic is a door that was clear coated. I sanded through the clear coat and ruined the blue line. How can I fix that ? Respray the blue and the black that is above the blue ? Do I scuff or sand ? Should I respray the whole door ? Any help ? Thank you very much.
