Even on the Diamon-Fusion website, they don't make those claims for their product. Here is what is says:
It has been proven by independent studies that a hydrophobic coating such as Diamon-FusionŽ, applied on car windshields and side glass, improves visibility during rainy conditions over 30%, giving an additional second of reaction time to the driver and improving response time by 25%, which translates into an invaluable safety feature.
In other words, a hydrophobic coating (Rain-X, Aquapel, etc.) does this-not necessarily only thier coating. A hydrophobic coating improves visibility during rainy conditions...No sh*t!
I don't know about thier makes it harder claims-I don't know a lot about nano technology, but guess I don't know how a nanocoating repels rocks
Definitely pass on the $495 wax job. And I would probably pass on the glass treatment as well-unless they let me throw rocks @ a demo car to see if I could break it.
