King 3B Trombone Restoration
You can see that the tuning slide has some lacquer loss. Especially in areas where there were previous dents that were removed. Lots of scratches in the brass as well.
We make sure to keep away from the engraving. We generally leave those untouched and just lightly buff and polish. Preserving original engravings and markings are a high priority.
Once we get the sanding marks out, we polish the horn to a very high shine to see what all we missed. And the process starts over again.
