The horn was played in South Florida and sometimes near the salt water :-( - but it's how I make my living.
When the patina started I tried polishing it, but it was a losing battle. I was spending more time polishing than practicing and it still grew faster than I could keep up with it.
So I got another sax and used this only for outdoor gigs, quit polishing it, and you can see the result.
I would never-ever purchase a bare brass horn. But I live and gig in South Florida near the Atlantic Ocean. There is salt in the air here and salt plus copper equals green.
My newest horn is a MacSax Classic covered with 2 coats of silver colored nickel.
I sold the Couf and use my gold plated Grassi as my outdoor horn now. The gold plating is coming off in places, and in frustration I even started to use Brasso on the spots, but I can see it as a losing battle.
