RINSE-N-WAX is exactly what says. After you wash your car but before you dry it. You simply spray each panel with RNW then spread it around each panel using the hose or pressure washer. RNW instantly bonds with the paint giving you shine and protection for 2-4 weeks! Never has waxing your car ever been easier. RNW also dramatically helps drying your car as the water literally falls right off the paint for easy drying. This is a 16oz Ready to use spray bottle.
