I went through this last fall with a Browning Silver Shotgun. I just called the Browning service folks in Arnold, MO and discussed it with them. They gave me some different options for camo finishes and i sent it in. My shotgun came back looking brand new (and i had used it quite a bit on the salt). They even replaced a few parts on the gas piston free of charge. I was a bit skeptical going into it, but completely happy in the end. I should have done it sooner. They had my gun for about 3.5-4mo total door to door if i recall.
