Touching up a scartched Steelbook

[Dynamo of Eternia]

Is there a way to touch up a scratched Steelbook? Maybe using automotive paint or something?

I recently aquired a Steelbook for well below the going rate and all in all in pretty good condition, except for some light scratches. The area where the scratches are located is mostly black (matte finish), so it's not like I'm trying to match up a ton of colors. I realize it probably won't look perfect, but if I can get even remotely close to the color of the Steelbook, it will look better than having these little silver marks showing through an otherwise mostly black Steelbook.
