This polish is a true wonder. I have tried it on hybrid coverstocks with great results. In fact it's as if the polish wasn't even on the ball, very transparent on the lane. I own a Hy-Road (Storm) and use it when it gets slightly dull. And it doesn't take much product to get a great shine. A quart will last a very long time. I personally recommend a ball spinner with this item, much easier to manage and better results.

I have this polish on my Natural (Storm), a U2 urethane ball and it picks up spares very well, slickery.

Again, a very transparent polish. I give it a must for those who like shine without sacrificing friction.
