considering oob is 400 wetsand with polish, you can imagine 4000 abralon plus polish isn't gonna wrinkle. I've tried numerous different surfaces on my smash zone, including 4000 plus polish, and none gave me a reaction better than oob. 4000 no polish was similar to oob, but a little weaker on the back.
