Unless it's just a shadow/lighting issue, that bezel looks to have taken a pretty good hit. Not sure if that will buff out (if your intent is to bring it back to like-new condition).
There is one on eBay currently that you might keep an eye on. It looks to be in fairly decent shape, and may save you some headaches and/or man hours trying to fix the original:
