I keyboard that gets used will look used. I think you should remember what Ripster said. Now you won't mind the shiny space bar effect in 6 months. OCD only robs joy. I know a little about this. Just use it and enjoy. Your keyboard now is "unique". One of it's kind.....Oh, a "limited edition". =)
I'm still playing with my new keyboards and don't have these problems yet but may wish to do something about it when it happens, I don't know but I'm determined to be content just in case there's no easy fix. That's my advice anyway.
@Ripster,
What's IMSTO?
