A composition is provided that restores and protects substrates to which it is applied including trim, headlight, or tires on vehicles. The composition includes reactive silicone silanes, graphene, and an adhesion promoter all dissolved or dispersed in a carrier oil or solvent. The composition forms a high adhesion high cohesion film that protects the underlying substrate from the adverse effects of ultraviolet (UV) rays, heat, rain, snow, and other environmental contaminants. A process of applying the same is also provided.
