This is my wife's car. It has been coated for over 8 months. Not always able to wash it like I should but the Nano Coating stands up no matter how long I wait to wash it. This protection rates at a 7 on the Mohs scale, which is the hardness of quartz. The science behind this is difficult to explain, but the performance of the product speaks for itself. Please email me to order your 5-kit special. Thanks - Dave@PearlUSA.net or Call: 808 779-7163
