I've heard of a bunch of guitars with maple necks having stability issues when left without a finish, but when the finish is stripped, either through a relicing process, or naturally over time, i've never heard of any stability issues. What especially comes to mind are the relics or old guitars that a lot of touring guitarists use. It seems like their guitars would especially need a finish going from one climate to another so often, but they continue to play the same guitar night after night without issues. What gives?
