This is necessary. There are eight advantages of sticking automotive film: 1, reducing heat loss, effectively reducing heat loss in the car in winter, and reducing heat loss by about 34% with high-quality thermal insulation and explosion-proof film. 2. Filtering glare can effectively filter the glare of sunlight and the glare of two cars meeting at night. Improve comfort and safety. 3. Blocking ultraviolet rays is the main factor leading to skin burns, skin cancer and the fading and deterioration of automobile dashboards, seats and textiles in the solar spectrum. 4.

Professional thermal insulation and explosion-proof membrane can block 50-85% of solar heat, significantly reduce the temperature inside the car and improve the comfort inside the car. 6. Enhancing the special structure and super adhesion of the anti-theft heat insulation explosion-proof film can greatly enhance the strength of glass, improve the impact resistance of glass and delay the time for thieves to get their hands on it. Experiments show that, according to the statistics of the police, 10 second is enough for criminals to be frightened and give up. 7. Privacy Many car owners have high requirements for privacy.
