How long after car window tinting can ETC be installed?

It is best to install ETC one month after car window tinting, because ETC uses a strong adhesive label that is directly attached to the car film. If the film is applied for too short a time, it may cause partial detachment of the film from the glass, resulting in an unattractive overall appearance of the car. The fully automatic electronic toll collection system ETC is one of the service functions of the intelligent transportation system, especially suitable for use on highways or in busy bridge and tunnel environments. ETC is an electronic toll collection system that allows vehicles to pass through highway or bridge toll stations without stopping to pay fees. It uses dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, along with computer networking technology for backend settlement with banks, achieving the purpose of toll payment without stopping.
I just had my window film installed and immediately went to mount the ETC device, only for it to fall off within two days—so frustrating! The film shop technician later explained that the windshield film needs time to fully dry, otherwise the adhesive won’t hold properly. He said in hot weather, it’s best to wait at least three days, while in humid or rainy conditions, a full week is needed. If you’re in a hurry, turning the AC on and directing airflow toward the windshield can speed up drying. However, some newer ETC brackets now come with suction cup designs, allowing earlier installation, but most still require waiting until the film’s adhesion stabilizes.
