A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorinated urethane additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.

Method for achieving recoat adhesion over a fluorinated topcoat

A coating composition containing a film-forming organosilane polymer, optionally a non-aqueous dispersed polymer, and a crosslinking agent selected from one or both of an organic polyisocyanate and melamine crosslinker. Fluorine functionalities are incorporated in the organosilane polymer to enhance soil resistance and cleanability. The coating composition can be used as a clearcoat over a conventional pigmented basecoat. The coating composition provides improved soil resistance and cleanability.
