I just used it. I can't tell you yet how well it works, but it wasn't hard to do, just time consumming. You first clean the wheel with their cleaner, let it dry completely, then apply small amounts of zoop seal that you mixed up a few hours earlier. Let it set for an hour or two (however long it needs to dry) and then apply their "hardener/polish" stuff to it to remove the zoop seal and bring back the luster. All in all, you can't tell a difference from before and after in terms of shine. If you use it do yourself a favor and only mix half or less of the bottle. We have the 4oz bottle and we have done 2 15X4 wheels, 2 15X3.5 wheels, 2 15X10 wheels, 2 17X9 wheels, 2 17X10.5 wheels, 2 calipers, 2 alternators, and a variety of other stuff and we still have a little less than half the bottle left!!! We mixed it all up though. Make sure to have microfiber cloths though for polishing/removing he polish as they will not scratch, all others will... trust me on this.
