as has been written here several timies: Paint Touch would not be effektive.
It looks like the allu at the wing also has some scratches so Best way is to as some paint shops.
I understand your feelings quite well - but there are more expensive mistakes one can make.
I remember that it took me only two days to let my hood scratch my New Morgan Park stearing wheel.
I did see this marks on every trip and when I did not look at tbe scratches I did feel them.....
