Abstract
The present invention relates to a system and method for cleaning and/or treating a surface, preferably surfaces such as ceramic, steel, plastic, glass and/or painted surfaces such as the exterior surface of a vehicle. In one embodiment, the method forms a transparent, hydrophilic coating on the surface of a vehicle. This embodiment of the method includes the steps of: (a) providing a vehicle having at least some surfaces that are at least one of the following: cured painted surfaces, cured clearcoat surfaces, and glass surfaces; (b) applying a non-photoactive nanoparticle coating composition to such surfaces; and (c) allowing the coating composition to dry on such surfaces before the surfaces are contacted by water.
