Car wax is a waxy substance that is rubbed onto a vehicle's exterior. It is then allowed to dry before being wiped off, creating a protective layer for the vehicle's paint and clear coat. Car wax is usually made from a mixture of carnauba wax and other natural waxes. The carnauba wax comes from the carnauba palm tree in the Brazilian rain forest. The tree produces the wax to coat and protect its leaves to keep in moisture during hot weather and is harvested only during certain months throughout the year. Car wax is used in the same way to protect the exterior of a person's vehicle as the carnauba wax is used to protect the carnauba palm tree.
