One of my crown inlays on my Spector Rebop has a dull look to it if your looking straight at it, if you look at it from the side it looks normal. Anyone ever had this problem? I think I might have scuffed it when I was restringing it awhile back, but I'm not sure. I guess my main question is if there is anyway to buff and polish it and what would I use. It doesn't effect anything is just purely cosmetics, and I'd like to restore it.
