I have a sax with about 15% lacquer, and when I was at my sax lesson today, the repairman asked me if I ever polished up my 48' Martin before. I wasn't aware that this could be done, and he spot tested and put some Brasso on the bell of my horn. Now I have a 2x2 inch spot where the horn looks shinier and newer, but the rest of the horn does not match. I might be interested in hand polishing the horn but realize this may take several hours to do it correctly and also I am not sure how it will look once the tarnish comes back or how long it will last with one application of brasso. I am kind of regretting letting him spot test it. I feel like now I need to do the entire horn or else I will have this 2x2 inch spot that stands out from the rest of the horn. Will the tarnish come back and blend in or should I hand polish the rest of it with Brasso? Also, after the Brasso application, it looks much different in color (like a new Yamaha) than the original lacquer did so it would not match with the 15% that is left.
