So, today I accidentally let my MBP slip from my hands as it was coming out of its bag. Fortunately, this was about an inch of falling height, so no *real* damage has been inflicted. Unfortunately, it came to rest on the metal leg of my desk, and now has a few small, thin scratches in the cover. Is there any sort of product/technique to repair these things? It's not a substantive issue, but I'm a vain and fickle Mac user, and I like my products pristine. Any advice?
