No first hand experience but I'm into cars and have a 2010 Challenger. I'm active on the Challenger forums and have read a lot about these coatings. Lets just say I'm a skeptic of stuff like this but I have generally read good things about them. I've heard if you don't apply it correctly it can end up kind of streaky. My opinion is any quality wax will do the job, it just won't last as long. A lot of the benefits of a wax isn't this magic coating on your vehicle but the fact it cleans the paint really well. A lot of body men don't believe all the wax hype. I will just say if you clean and wax your vehicle once or twice a year it will help a lot. I'm also a big believer in clay bars for cleaning the vehicle well.
