Car wax is a protective coating applied to the exterior of a vehicle. It is typically made from natural or synthetic materials that create a barrier against dirt, UV rays, and moisture. By filling in tiny scratches and imperfections, car wax helps to enhance the shine and overall appearance of the car's paint. Applying car wax is a straightforward process that involves cleaning the car's surface, applying the wax with a soft cloth, and then buffing it to a shine. Regular waxing can prolong the life of the paint and keep the vehicle looking new, making it a popular maintenance practice among car owners.
