Still if you feel your nails go inside the scratch. To avoid repaint job you can go to a good painter ask him to rub it with 2000 grit sand paper with water. Than with electric polisher compound and polish it. It will become much better visually. Do not try to fill it as it will look ugly. A picture will elaborate much better if you can share.
After that still if at some places it is more chipped off, you can apply touch up.
