Has anybody treated their Commander with Xzilon? My wife just bought a new car and the dealer was trying to get her to get it applied to the vehicle. The sales pitch sounded almost to good to be true. Never have to wax, spray paint wipes off, etc. It can even be applied to the interior to protect it. Some quick web research this morning didn't lead me in one direction or another. The down side I see is that to take advantage of the warranty everything has to be done at the dealer.
