The exposure of car paint to sunlight, rain, car washing, and daily environmental pollution, as well as gravel splashing while driving, can result in scratches and damage to the car's paint over time. The paint protection film provides invisible protection by forming a tough, transparent protective layer on the surface of the car's paint, effectively preventing paint damage and keeping the paint glossy and vibrant. Traditional car maintenance methods often involve frequent car washing and waxing to maintain the gloss of the body, but this approach can lead to scratching of the paint surface due to lack of hardness and dust adherence, accelerating oxidation and corrosion, resulting in the car losing its color over time. Additionally, waxing cannot effectively resist UV rays, making it difficult to protect the paint surface. Furthermore, using polishing to remove fine scratches from the body will make the paint thinner and may eventually require repainting, leading to a significant depreciation of the car.
