[arnage]

does it feel as if it's a scratch?... i.e. - running a fingernail over it, is it completely smooth, or you can feel a detent?

note that you may want to try a few different types of pencil erasers. the pink / gummy erasers may not do as good of a job as the harder ones (to get more technical, i.e. a pentel white "high polymer" eraser), with removing the material.

I suppose worse comes to worst, you can send it in for a bezel replacement. I suppose it won't come particularly cheap, but at least it won't bug you into the future.
