C3 Wax Guard contains a proprietary blend of carnauba wax and silicone polymers, which provides a binding protective layer on any surface, promoting water repellency, beading, and lower water roll-off angle. This reduces soil deposition and thus keeps the surfaces clean for a longer period of time. Wax Guard also contains UV inhibitors to further protect painted surfaces from harsh sun rays, prolonging the life of painted surfaces. Use Wax Guard following exterior cleaning in conjunction with your secondary rinse.
