Re: Flitz Polishing
Tiny little brown or rust colored spots on a lacquered horn could be acid bleed, if that's the case I don't think there is much you can do for it. It's a victim of not being properly de-greased at the factory during production, a small spot of grease or oil left on the horn before lacquering will leach to the surface later causing those spots. Most often seen at posts or tone holes or anywhere where the grease can pool during the manufacturing process.
