That was my thought too. I'm not even sure the nail polish would effectively stick to the contact paper. I'm hoping that if I don't like how it turns out or it doesn't hold up that I can just peel it off. My only concern is that the sticky stuff from the contact paper gets left on my battery.
For the record, I have used clear nail polish on my stainless eGo, not liked it, and used nail polish remover to take it back off. Doesn't seem to have negatively affected it

(I also tape off the button/connection area before doing any of these things)
