A surfboard application is the process of applying WAX to a surfboard in order to increase its grip and reduce drag. WAX is a type of material that is applied to the top of the board, usually in a circular motion, to create a thin layer that helps the rider stay on the board. It also helps to reduce friction between the board and the water, allowing for smoother rides. Waxing a surfboard is an important part of surfboard maintenance and can help to extend the life of the board.
