hi. When you say crusty, did you mean it was a crusty and you cleaned it to this point? I am asking because it looks like someone treated it for
bronze disease. I'm not sure if the poc marks on the
face are dig outs from damage to
bronze disease, (they certainly don't look like centering dots) but I don't see how you could improve it without doing something (filling) that most of the posters would say goes beyond simply cleaning it. Maybe some of the super pros could offer advice.
