The coating is developed on an nanotechnology base, this means that a connection is made with the lacquer layer at a molecular level. The image below shows how an old weathered surface after treatment became flat again and less susceptible to dirt and moisture. During the treatment a thickness of 3 nm (nanometer) coating is applied which creates a glass-like structure, so that the treated parts will become more scratch-resistant. This layer is invisible to the eye.
The coating provides a super hydrophobic effect which is also known as the lotus effect. Water drips roll of the surface because of the flat substrate, when they roll off the surface they will take the dirt with them. The image shows that dirt on the treated part will go off easily when you clean it with water.
