I re-used a nut fitted for a different neck on my new to me one. It didn't sit properly so used a small strip of blu tack to hold it down.

Its been fine since I did this months ago but am worrying now if blu tack has any moisture in it that could damage the neck?

What do you think??

Thanks, Luke.
Any moisture in the blue tack is not going to damage the neck,

It would probably be better to tack the nut down with a bit of wood glue.
