Recrown the frets
Leveling will leave flat tops on the frets. Use a fret crowning
file to restore their rounded shape.
Reapply blue marker to the fret tops. By filing the sides of the
frets, bring in the edges of the flats left over from leveling.
With a rounding motion, keep bringing in these edges until
the remaining flatted top is a very thin line. Don't remove
this line entirely; filing the fret tops would undo your leveling.
Sand the frets with 400-grit, then 600-grit sandpaper
wrapped around a foam block, running up and down the
entire length of the fretboard.
Follow up with Light Duty Scotch-Brite Pads or 0000 steel
wool for a final finish. This will remove any of the remaining
lacquer from the frets, and polish them to a smooth finish.
