RejeX is a thin-film polymer coating designed to provide a high-release surface. This very thin film less than a micron thick - prevents stains and adhesion of common contaminants such as exhaust, bugs, oil, tree sap, bird droppings, road grime, brake dust, etc. It also makes graffiti easy to remove and can be applied to windshields to repel rain. It's easy to apply and produces a deep, lustrous shine that outlasts the most popular waxes by months.
