I recently bought a Getzen Super Deluxe Cornet on ebay. The description was perfect and the horn plays great. However, as the description mentioned it does have several "pin" holes in the bell flair from where repairs were made. I have seen patches on bells and I've replaced bells. But these pinholes are so small that you can only see them with light behind them. Could they be filled with silver solder. I have a friend that is a jeweler and said he could give it a try. Is this a bad idea?
