What are the reasons for severe internal reflection after car window tinting?

[SanJosie]

Severe internal reflection after car window tinting may be caused by poor-quality film with high reflectivity. Precautions for car window tinting are as follows: 1. Film selection: When choosing window film, in addition to brand and quality, the most important factor is light transmittance. It is advisable to select films with over 85% light transmittance, as traffic regulations require a minimum of 70% light transmittance. Films below this standard will fail vehicle inspections and may affect driving visibility. 2. Post-tinting care: For three days after tinting, do not roll down windows or wash the car, as the adhesive needs time to cure properly. Operating windows during this period may cause the film to peel or form bubbles. For vehicles with sunroofs, avoid opening them for three days, especially during highway driving. Avoid using strong adhesive labels directly on the tinted surface for one month to prevent localized detachment from the glass.
