No S-845 Speed Wax is designed to maintain and enhance an existing coat of any Collinite Sealant Wax (845, 915, 476s). While it does not replace the durable base coat durability found in one of our waxes, it does offer its own stand alone protection of up to 2 months. It can be used as often as desired to boost beading and provide a slick showroom gloss.
