ETC should be installed one month after applying the car film, because the film on the front windshield generally takes about a month to fully dry. If ETC is installed before the film is completely dry, it may cause partial detachment of the film from the glass. However, some brands of films can dry completely in about a week. Therefore, in practice, it is necessary to analyze flexibly based on the actual situation. Additional information: 1. It should be noted that most metal films can interfere with ETC, affecting the ETC signal, which may result in the toll station being unable to read the ETC, triggering an alarm for 'non-ETC vehicles entering by mistake' when passing through the toll station. 2. ETC refers to the Electronic Toll Collection system for highways.
