Fretboard and neck mod/repair - replacing clay dots and side markers

[leftyaxeslinger]

So....I have vintage style tele copy and the clay dots are not only hard to see, but literally crumbling. Is there an easy fix for this or is this a job for a luthier? Also what side markers? Any decent decals out there or tricks for something that will actually stick to the side of the neck through all the sweat and abuse?
