Aha, I think I may have found something. Check out what this says:
Rubbing out by hand
The final step is to eliminate all traces of buff marks - leaving only a perfectly clear liquid black finish. This is easily accomplished by making a one-inch, six layers deep square of high quality facial tissue and putting a dab of three- or one-micron diamond on it. Then dampen it slightly with denatured alcohol and very gently rub the surface in two-inch strokes or less, exactly as if you were waxing a fine vintage car.
Don't give in to temptation and press harder to get out certain buff marks and don't use strokes longer than two inches or scratching the surface becomes a real possibility. You might be forced to press down harder in some areas, but do so reluctantly, as a few extra minutes rubbing by hand is faster than going all the way back to a hard buff to get out a mean scratch. It also is helpful for you to be in as clean a room as possible when buffing, as grit constantly falls from the air in most shops and loves to put deep scratches in optically polished surfaces. Also be sure that your light fixtures are clean before buffing, as this one source accounts for more than half of all dust contamination.
Once hand rubbing is complete, wash off everything with more denatured alcohol and soft tissue.

Diamond paste is pricey, but worth a shot. I think I'm gonna try this out myself.
