Btw, found THE method for polishing the neck to a silk smooth, non-sticky finish:

1. Sand lightly/very lightly with 320
2. Wetsand lightly with 500
3. Wetsand lightly with 1500
4. Polish with the center puck of a floor pad (like a scotch brite but less aggressive)
5. Wipe off and enjoy a fantastic surface (the neck was previously spray coated 3 times with an acrylic clear coat)

Did the same on some other guitars and the result is fantastic!
