Slack the strings a lot, pull three strings off to each side of the fingerboard, tape behind the neck. Adjust the fingerboard flat by adjusting the neck truss rod (you'll need a special fretboard level that has cutouts for each fret). Tape off the fingerboard, color the fret tops with a marking pen; using a steel level with 320 grit on one side, and 600 grit on the other.
Add 4 layers of tape at the 10th fret, re-color the fret tops from the 11th to last frets, add in "fret falloff" that's necessary for string clearance at the high frets. Put a piece of tape over the abrasive where it will contact the 4 tape layer so that won't get eaten up!
Cleaning off the frets with naptha (lighter fluid).
Re-color all fret tops, use a diamond crown file (lubed with Pro-Cut) to round off fret sides; a slight flat is left on the fret tops - this will round off with the later "hand honing" process.
Rounding off the fret tops with 600 grit Klingspor paper. Buff the fret tops with a rapid motion from the first to the last frets, up and down the neck.
Using a round ended, hard foam rubber backing and Micro Mesh abrasives, 1500 grit through 12000 grit, to hone and polish the frets. Use the same first to last fret buffing motion.
Ready to play!
