I had problems with this finish on a taylor trumpet. It got mildew (black dots all over) and they would not come off. This has put me off this sort of finish or indeed the equivalent silver. At least with Bright Silver Plate you can polish things out if all else fails. You can also replate BSP quite easily, satin or scratched finishes i am not sure about refinishing. So i am thinking through what finishes I would accept on a new instrument. Brisht silver plate would be fine. What about raw brass? How durable is that? Does it stain? Just interested in starting a discussion and getting other peoples views. I definitely don't like laquer, I like my instruments to be metal all the way through.
