Many people underestimate this property - but in vain.
Look, if you apply the coating, how to understand what it is on the paint, given the thickness of a few tens of nanometers? No way! Eye you will not see such a thickness, and the microscope is not everyone has. Due to this property we can understand whether there is a protective coating or not. Think, it's been six months (at best) and the manufacturer says that there is no hydrophobicity and that's fine, because the molecules of the coating penetrated into the paint, made him stronger, and hydrophobic coating, which on top was applied, obsolete, etc. Is a fraud! The hydrophobic layer is applied an hour later, "ceramic" substrate and it 100% needs to adhere with it and hold as long as the substrate in place. On the roof, on the trunk and above the level of the moldings, the coating must be. If someone asks you to use amplifiers hydrophobicity is a fraud. Yes, someone earns according to this principle, but it's sooner or later will be revealed, what then?..

Conclusion 1: The stronger hydrophobic molecules sewed in the coating, the longer the self-cleaning effect and Vice-versa - the longer there is a hydrophobicity - the stronger the coating itself. You know? Hydrophobicity is an indicator of the quality and durability of the coating.

Conclusion 2: Hydrophobicity allows transport less dirty on the sink when drying with rags to help create a more thick water cushion between the cloth and coating, reducing the burden of small abrasive particles to the surface. This property (in high-quality protective coating) reduces the degradation of the varnish in the scratch, allowing even zatsarapannoy the surface layer to remain transparent and shiny, while maintaining the decorative properties of processed transport for many years.
