Is it necessary to tint car windows?

[GemmaAnn]

It is necessary to tint car windows. Here are the specific instructions regarding car window tinting: 1. Precautions after tinting: Do not open the sunroof within three days, especially when driving at high speeds; avoid rolling down the windows within three days after tinting; if bubbles appear at the edges of the film, they should be repaired at the installation site within 24 hours. If this time is exceeded, the edges of the film cannot be adjusted because the adhesive around the bubbles will have dried, which will inevitably cause wrinkles during the repair process; do not wash the car within three days. 2. Misconception: The darker the film color, the better the heat insulation performance is not true. The infrared blocking capability of the film is not related to its color but depends on the reflective effect of the metal or oxide sputtered layer. Currently, the best reflective technologies in films are the indium-silver oxide sputtered layer and the indium-zinc oxide coating, both of which can achieve over 90% infrared blocking rate.
