Formulated with a selected blend of surfactants and pure waxes. Ideal for cleaning, polishing and drying bodywork in one application. Formulated specifically to combine cleaning and degreasing, effective polishing and easy drying. Self drying: rinse water collects in droplets and flows easily down the body, making it quick drying. When used to wash cars that have been previously treated with a polish, it maintains protection longer. PETRONAS Durance Wash & Wax contains silicone.
