Carnauba Wax, probably the final thing most detailers will apply when it comes to cleaning your car. The highest grade is yellow, often refined further to pure white. Some formulations are hard, some are soft. Often coloured as well for lighter cars, or darker paints. Softer car wax polish can be applied by hand, rather than an applicator pad. Carnauba Wax gives the deepest glossiest shine, and is usually the choice of concours detailers.
