I have always wet sanded everything. If I don't use water, then the heat created is so hot, I can't stand to put my hand on the ball. The water act as a lubricant and a coolant I would say. Also, the reason I wet sand everything is because I once tried, by hand-no spinner, to sand a ball, and the lines I left in the ball were HORRIBLE! Granted, I was only a kid (it was the original Red Zone when it first came out--10 years ago or so?)It took the pro shop operator about 2 hours to fix what I did and then to resurface the ball. I said I WOULD NEVER do that again, and I haven't.
