Car wax allows car wax to be used as wax-hardeners and shine enhancers. When car wax is applied, it provides a thin layer of protection to the clear coat of paint on top of the body. Individual components like tree sap, road salt, ultraviolet rays, rain, hail, snow, sun, wind, and bird droppings can damage the paint on the car. This product helps to protect the body from exposure to these harmful elements so it will hold up against time.
