My only experience with "Ceramic Waxes" was two years ago on our little AMG.I think it was Meguires. You sprayed it on after washing and rinsed it with strong steam of water. Every bottle of it just about on the shelf leaked through or ate though the plastic bottle bottom. I didn't know it when I bought it though. One guy at the Mercedes dealer only washed my vehicle. He put ton for me. It shed water and bugs easily and the shine was great. I bought it because I have difficulty doing anything and I would have to wash the car myself. The car has set in my garage for two years minus three excursions and to the dealer for service B.
It needs washing now, and the Mercedes Dealer has quit hand washing cars and installed one of those auto brush systems. So today or tomorrow I will do it myself and I'm particular.I'll see how much of the shine remains. I'll hand polish and wax with Meguires spray polish and spray synthetic wax only because that will be my limit and until I can find someone who knows not to use dirty mitt or brush and not to dip them int o dirty soap solution, to wash a car and cares about his work. The wax worked but on spotless finish. I normally would not think of using such a wax. The car is 10 years old but looks better than the new Mercedes. New Mercedes don't have real glossy finishes. They are water based paints and the clear coats too apparently.
