I got a good deal on a 686 (no dash). Someone did a really nice job of polishing it and it sparkles. It is not nickle plated. It is stainless steel. Question: is there a way to get it back to the pre-polished look? Polished looks nice but I think the original looks is good, too. I am just curious about this, if I ever wanted to do it. Thanks in advance for replies.
