Get a touch up paint, a little bit of wet sanding, polish it with a porter cable...
It will not be as perfect as it was before... but it helps... good luck!
Here is what I found under
Detail Section (Sticky)
Q: What if I have scratches that I can feel with my fingernail. How do I go about removing them?
A: You’ll need to fill the scratch in with touch up paint and wet sand the blob down using a particular grit of automotive sand paper. Once that is complete you’ll need to polish out the sanding marks with a finer polish.
