So I have a 2009 MBP that I got at the end of 2009. It seems now on the right side on the front edge of the bottom case the metal is just gone, like its pitting. Its really hard to describe what is happening but when you run your finger over it you can actually feel it. Anyone ever heard of this happening? I have also never once dropped or hit this laptop with anything, I am pretty protective of it and am always careful. Any ideas?
