I'm the type of person who really takes care of their property. I clean my mbp weekly and try hard not to scratch or welcome any imperfections to this beautiful hardware. But I have this friend, who has always managed to ruin everything in my life. I allow her 5 minutes on my $2000 computer, and she throws her phone on the keyboard. But no big deal, no visible damage, that is until you turn the backlights on and my F key is now one big shining imperfection and it's distracting. I was wondering if anyone had any ideas on how to 'fix' this. I thought about using a permanent marker to fill in the chipped area, maybe acrylic paint? I also saw a few websites offering individual keys that I could replace. Am I being too anal, or do other people care about this stuff as much as I do?
