It looks like it has gone through the clear coat and damaged the colour coat underneath.
If that’s the case then the Dupont Scratch Repair Stick won’t touch it I’m afraid.
The DuPont Repair Stick is basically just very thinned down clear coat that acts as a filler on light scratches in the clear coat to stop them disturbing the path of the light to the colour coat beneath.
But being very thinned down it won’t last all that long anyway, so it’s only a temporary measure really.
The colour sticks are even more temporary, they are basically a hard wax with a pigment added that fill the scratch.
A crayon the right colour would do a Similar job 🙂
But if it’s broken through the clear and damaged the colour, the scratches can’t be removed by machine polishing, so I’m afraid your only two real options are to have it painted, or leave it
