My trumpet has tiny little bubbles on certain parts. It is a year old eastman. I am concerned they will get bigger and ruin the finish. What are they and how can I fight them? trumpet UPDATE: Took the trumpet to the place I got it. They insisted it was due to my fingers. Is it possible that the oil on my hands can ruin silver plating in a year? The best part was the dots are not in the location where I put my hands. He took the trumpet to the shop 2 hours away ( I don't know what they can do) . The man was very eager to say he dots were my fault.
