buy the most rugged panasonic though book notebook: you can put it in water, jump on it, roll on it with a car or use it as a crazy carpet for snow sliding and they're still fine. Sure it's a little expensive compared to a keybord but they should resist to your crazy use.
I looked on duplicolor's site and just saw that they don't have many colors in their metalcast product line so I guess yours is the only red. Anyway, once agin, nice paint!
Very nice paintjob dude.(What else can I say?)
I agree with you that this gray part of the mouse sucks fin term of wear resistance. Look on that picture, I highlighted a shitty part (the soft pad in the base causes that black spot):
Mine also does that and it's so ugly... I'll have to...
