Does Secondary Window Tinting Cause Significant Damage to the Car?

[Richardson]

Secondary window tinting does not cause significant damage to the car, as the most crucial step in the process is to thoroughly clean off the adhesive residue left from the first tinting. If not handled properly, it might scratch the glass, affecting only the appearance. Below is relevant information about window tinting: 1. Windshield Film: When choosing windshield film, avoid products that contain heat-absorbing agents. According to regulations in China, the light transmittance of windshield film must reach 70%. Clarity and safety are the most basic requirements for windshields. Adding heat-absorbing agents to the windshield is like having something in your eye—it can impair vision. 2. Rear Window Film: It’s important to note that rear window glass is different from other windows. The rear window has heating wires, which are printed onto the glass during manufacturing by the car manufacturer and are inherently fragile. If the old film is not removed carefully during the process, the heating wires can easily break, resulting in the loss of the rear window defogging function.
