I've read posts about people using "Hard as Nails" nail polish to protect the shooter lane and scoop edges (when cliffys are not available). So I picked some up. Is this the right stuff? How much to apply? A light coat I would assume. In the shooter lane, just spread some on the area where the ball kicks out? Is it removable? This will be going on an acdc premium, so I'm a little nervous to use it. I have the cliffy for the shooter lane and the protector on the other side, do I still need to use it there?
