I have the StewMac fretboard protector thing that goes under the fret crown when pulling frets....I heat up the fret with a soldering iron...I have the StewMac fret pulling plier things. On paper I'm doing everything right. But I'm still getting some chip out on both rosewood and maple. Actually, pulling the frets seems to go fairly well but on these last couple of jobs I've had to deepen the fret slots for the new frets going in and that seems to be where it's happening I think. Not huge chips but enough that they will slightly peek out from under the new fret wire which is even wider than stock. I just can't seem to control this damn chipping!! So I'm thinking that from now on after pulling the frets I will use a toothpick or something similar and just run a small bead of super thin CA glue on either side of the slot....particularly if I'm having to saw the slots deeper. What are you guys doing out there to prevent this chipping business?
