Is Waxing Once a Month Harmful to the Car?

Waxing every month can damage the original wax on the surface of a new car. The advantages and disadvantages of car waxing are as follows: Advantages of waxing: Heat protection. Car wax itself can reflect incoming light from different directions, preventing the light from penetrating the clear coat. This prevents the base paint from aging and discoloring, thereby extending the lifespan of the paint and preventing fading. UV protection. Similar to heat protection, ultraviolet rays from sunlight can damage the car's paint. Car wax can minimize the harm caused by UV rays to the paint. Disadvantages of waxing: Prone to oxidation. Car wax uses petroleum as a solvent, making it highly susceptible to oxidation. It typically begins to oxidize in about half a month and fully oxidizes after a month, meaning it cannot provide long-term protection for the paint. Paint wear. If the waxing is performed by an unskilled technician, it can easily result in fine circular scratches on the car body.
