If you have a fretboard that has depressions worn because of fingernails, is there a way to fill the depressions and level them off with some kind of synthetic/composite/compound? I know this sounds loonie, but if you can fill in the string grooves in a nut without the filler breaking down or even showing, maybe some day there will be fretboard filler like bond dough on a car.
