Have some, tried it. It goes on like water, not like polish. There's a spray that removes after you're finished bowling. I tried it once, didn't seem to get much more length. YOu spray it on, let it dry, and wipe the ball off. It's legal for use during bowling. The labels says "it seals the ball's surface from oil". I guess that means it prevents the ball from absorbing oil. Supposed to get 4-5' more length. That's a lot. I suppose I should try it again, to be fair.
It's part of a 3 bottle test kit that also includes a similar spray to get the ball to grab earlier on lanes that are more oily than you expected. The 3rd bottle is a remover for both of those sprays. They go on easily, like water.
