Gee, to diminish the discord here, understand these are not A flat finish, but high gloss. A minor problem, but I would like them to B sharp looking, as they augment the look of the instrument, and sustain it's value.
(Don't fret, Dewey, you're still the head nut here)
And I am sure the IPA idea to improve the sound would work, especially if applied liberally to my audience.
But really, will Naptha harm the Gold?
