Coating compositions and methods for applying reactive silanol coating compositions having electron deficient surfaces when cured wherein organic radical groups from the silanes are forced to the surface of the coating. The interpenetrating silicon-oxygen structure below the surface skews the electron cloud downward creating a net positively charged surface which is hydrophobic and oleophobic to repel contaminants by discouraging light hydrogen bonding. The surface is also extremely tight and thereby absent nutrients for microorganisms, discourages organic growth. These unique qualities provide cleanliness solutions for automotive and marine applications, including substrates subjected to elevated temperatures typically destructive to organic coatings (paints). Substrate examples are: brakes to repel brake dust on wheels; coating of engines and engine accessories, high-temperature exhausts/stacks/eductors, and engine compartments; automotive, architectural, industrial, and marine exterior substrates; and preservation and restoration of vehicles and boat interiors, seats, and instrument panels/dashboards and the like.
