The nail polish has been in since 9/21/11 so hard to say for sure it works perfectly. I was not planning on mentioning it until I was more certain it worked for a long time. The ones I double coated are better than the single and the one that got a light sanding (300 grit) is the best.

I hope it works out for you so far so good. Let me know if you find some better combination perhaps it can be improved more.
