A couple of fret ends are not seated as well as I think is needed. Clamp with radius block then apply glue under the fret ends for the whole neck or just work on the specific frets that need it? Input from anyone appreciated.
I usually apply a couple of drops of thin superglue to all fret ends as soon as they are hammered in and seated correctly. But luckily so far I haven't had any "stubborn" fret ends to deal with. If it is just a couple of them, I would probably glue and clamp them individually and then put superglue on all the other fret ends afterwards. The fret leveling process will take care of the minor height differences later.
Is there anything in the fret slot that is stopping them being seated properly? If they won't glue/clamp into place, maybe need to pull them and re-clean / re-cut the slot?
But I'd only focus on the troublesome frets, not the whole neck.
