If its single stage, non-metallic, and the paint is thick enough you can definately fix it. Block sand starting with the finest grit that will level the surface (probably about 1200-1500) and go up from there. Compound to a glass shine.

If its metallic/clear, and the clear is thick enough, you can level the top surface the same way, and minimize the visual defect, but you may still be able to see the topography of the scratches in the basecoat.
