Hey, I recently bought a MIM fretless J, and it had some loose/buldging fret lines. SO I finally decided to try to take all of the fret lines out and fill the gaps with epoxy. It went well for the loose ones but some of them are still glued in pretty tight, and it looks pretty bad with a couple of lines missing/pieces still in the fingerboard.

Anyone know how to get these things out without ripping up my fingerboard?
