NuraFixNano Car Spray uses nano-coating technology, which involvesextremely small particles that bond with the car’s surface. Thesemicroscopic particles fill in tiny scratches and irregularities onthe paint, creating a smoother and shinier finish. The nano layeralso forms a protective coating that repels water, dust, and dirt.Because of this protective barrier, contaminants are less likely tostick to the surface of the car.
