Do you own an orbital buffer? Taking that out is going to require a cutting pad and some compound, and probably a finishing polish afterwards with a polishing pad if you really want to level down and remove the defect. If you cleaned it well and used clay and its all smooth, then it is etched into the clearcoat and won't come out with some correction work.
