I've had my HD for about 3 years, and the plating is wearing off on the head (actually on the corners of the edge of the flat plate). Is there anything I can do about this? Did I get a dud, or is just how they are? I figured to use this razor for many many years (maybe even forever), but the razor is rough where the plating is wearing off. I love everything else about this razor, but if I have to replace it every few years because it has rough spots, I'm not going to be too happy. Any thoughts on this matter?
