I used snap-on green touch up enamel paint and after it cured I used a mr clean magic erasure to buff off the excess. I tried the other way and couldn't get the lettering as crisp and as clean as my way, but if you want to do the nail polish and then clean it with remover and it works for you go for it. I happen to think enamel paint is harder and sure seems to last longer, It hasn't faded at all and I was able to do some of my accessories also without a problem. If the mr clean magic erasure removes your black anodization then you didnt have a very good anodization. On my sport you could never tell that I did it that way. But to each his own. It is still on my rifle if you look close and it is still just as green. Plus solvents havent done anything to it. The shade is called extreme green! thats the color of my snap on tool box
