Car wax is a protective coating applied to the exterior of a vehicle. It helps to create a barrier against environmental elements like dirt, UV rays, and moisture, which can damage the paint over time. Car wax can enhance the shine and appearance of the vehicle, making it look newer and well-maintained. There are different types of car wax, including paste wax, liquid wax, and spray wax. Each type has its own application method and benefits. Regularly applying car wax can prolong the life of the paint and reduce the need for costly repairs or repainting.
