Re-Silver Plate my Tuba MouthpiecePlating preparation and re silver plating for any tuba mouthpiece. Please note: Our plating and re plating process involves a thorough cleaning, polishing the rim and interior cup, and a light re polish of the outside of the mouthpiece. Imperfections, such as pitting, will not be removed as this involves removing material which will compromise the playability and feel of your mouthpiece.
