Hi I just came across this even though it might be a bit late I'll add to it anyway with the experience I had.
I did the same method wazkelly and zandit did however I probably didn't apply the TO correctly (34 coats & not enough drying time between each coat).
Following waz's advice after the last coat of TO I left it for about one month to cure. Then:
- used micro mesh pads up to 12000.
- cut and polish with meguiars ultimate compound.
The neck is nice and smooth and I'm very happy with the results compared to my first build where the neck was too "grippy" and not very easy to play.
