"but deep enough to see the white clearly"
Do you mean the scratch is through the paint and you can see primer? That can't be sanded out.
If the scratch is through the clear coat it can't be sanded out.
If the scratch is minor and will leave an acceptable amount of clearcoat and I planned to garage the car, I might accept having it sanded.
From the 09 Service Manual:
CAUTION: Do not remove more than 0.5 mils of clearcoat finish when sanding, hand buffing or polishing. Basecoat paint must retain clearcoat for durability.
