About a year ago I got a great eBay deal on a cheap telecaster with a flamed maple top, ash body and a maple fretboard. It is a budget guitar from kit quality parts and at the time I thought it would be a great project base. Unfortunately while the body is finished nicely, the neck and the actual fitting of the neck to the body were a disaster. The frets were way off the edge of the guitar, the neck needed some serious shimming and the finish was so thin on the neck and fingerboard that after a few minutes of playing, oil from the strings had stained the wood.
Keda five dye kit and applied it. The first coat wasn't very impressive.
Tru Oil which really made the dyed figure of the maple fretboard pop out from the field of the wood.
Two things didn't go perfectly. First, I sanded enough material off between the frets that in a few places, especially given the frets weren't seated well to begin with, you can definitely see a little gap between the crown, exposing the tang when you look at an angle. Also it's very difficult to apply Tru Oil to a board with frets on it without making a mess. I'd go slower if I were doing this again and consider thinning it out more as I left some white lines near the frets themselves that are visible only when looking closely.
