I think it is BS. I purchased it from my dealer and they said I did not have to wax my car again. It was guaranteed for 5 years. Anyway, a bird dropping on my roof left an etch mark and I wiped it off as soon as I seen it. After a couple of months of being garage kept, the surface is not as smooth as it once was and I do not believe it is doing what they claim. I am tempted to wax it but they told me if I did it would void the warranty. You be the judge. Anyone else have any comments on Xzilon?
