Ballastic hit the nail on the head. You have to try stuff to see what works for you. I can tell you I have long given up shoving a QTip stalk in a wheel bore. I could never get it to work. When I polish, nothing is in there snug or tight. Just a tiny bit of friction is all you need. And time, sprinkled with patience. When to buff out a wheel is also a tricky part to me. I don't blow them out after the initial wax; there are better ways to remove the excess wax. The best way is to get a bunch of scout wheels and given different methods a try; just slight variations from the black ice video. You'll have to figure out how to gauge your technique; putting them on a car works, but may not be the best method. I'm a visual creature, so I need to be able to see what's going on in there.
