You don't have to put on all the finish before the frets, just a coat or two to check that the surface is smooth and sufficiently sanded out. You don't want to have to do any sanding after the frets are in.
....Nexy, please forgive my interruption, but I would really like to ask Bruce to expound on this subject, if that's ok...
So then, it is ok to install frets on top of finish coats?
I wanted to do that on a maple boarded build I did, but I was concerned that seating the frets on top of finish would somehow make them ...unstable?.
So I sprayed over them afterwards. And of course due certain...circumstances ...I got some pretty intense orange peel texture that
needed to be sanded out. Thus began an extremely painstaking process of level sanding by starting at the first (widest) fret with a thin strip of wood for a sanding block...and hand planing it down to the proper width for each subsequent fret.
It came out ok...but I vowed to never do it again,
that way....
But, if is is acceptable to apply a thin layer of finish prior to fret intallation... would it be prudent to make sure each fret was thoroughly
glued in?
I'm not sure why I feel it would be dangerous to install (seat) frets on top of finish coats...
BUT if I need not worry...that would be fantastic!
Please share any reassurances if so inclined?
This is the maple board I spoke of.
I would love to do more....just not the way I did this one.
