I have the opportunity to pick up a 9' Brunswick Anniversary that I used to play on when I was in college. It's in great playing shape but there are a ton of circular dings in the tops of the rails (which I believe are walnut). I can get repro skirts/blinds and anything else that might be needed but how difficult will it be to refinish those rails? It seriously looks like someone attacked them w/a ball. I've heard that belt sanding can fix it but I would prefer to raise the dings as much as possible and sand as little as possible.
