If I were you I'd go to a body shop supply store and buy a spray can of color matched paint and some extra fine sandpaper in two grits (tell them what you are doing).

Prepare the area with the sand paper or sanding pads (better) clean the area with prep-sol or it's equivalent and sparingly spray the area twice with thin coats to avoid dripping etc. Maybe finish it off with a can of clear coat and call it a day.

Be careful to only paint the scratched area and don't allow over spray to drift onto any other areas.

It's only noticable to you and that's what matters. After that you'll feel better and won't even think about it.
