Nice save Stan. This one is a personal pet hate. I always seem to be doing it. Last you tube video I watched by a luthier in Sydney recommended actually leaving the thinnest sliver of binding "unmasked" along the bottom of the binding so that this didn't happen. I think I'll be doing the same next time I spray a neck.
Anyway, nice work. She's really coming together..!
cheers,
Gav.
