I have had an all maple P-bass neck laying around that I haven't put on my bolt on P body. Reason is I'm ashamed of myself and my Dad. He had a dull drill bit and kept pushing and pushing on it trying to drill neck-screw mounting holes on heel and drilled right through fingerboard! I have filled those holes, used different kinds of filler to hide the holes, but it's next to impossible. I have tried everything. Everytime I sand a little, there are the everlasting imprint of a hole once there, (but not so noticeable now) in the end of the fretboard. I am wondering I should just find a "paint" and hide the places for good, then put a clear finish on the neck and be through with it. Can anyone help.
