Finish flaw on rosewood fretboard - what to do?

[Planet Boulder]

Rosewood fretboard has a finish flaw in the form of a small fault between 1st and 2nd frets. This is not a "crack", per se, but an imperfection that just needs to be filled.

What should I use to fill it?

is it noticeable to your fingers when you play on it?
i know people use epoxy to fill voids and worm holes in burled woods...perhaps it would also work for you here?

another option would be to take the excess from cutting the fingerboard and make some dust from it then put some glue in the fault and fill it in with the dust..then sand it. i think that might help to patch it up cosmetically.
