How long after window tinting can ETC be installed?
2 Answers
It is recommended to wait one month after applying window tint before installing an ETC device, because the film on the windshield generally takes about a month to fully dry. If the ETC is installed before the film has completely dried, it may cause partial detachment of the film from the glass. However, some brands of film can dry completely in about a week. Therefore, in practice, it is necessary to analyze the situation flexibly based on actual conditions. Here is some relevant information about car window tinting: 1. The main functions of car window tinting are radiation protection and energy saving. The solar film blocks sunlight, especially infrared and ultraviolet radiation, effectively controlling the greenhouse effect formed in the sealed cabin, significantly reducing the fuel consumption of the car's air conditioning, thereby achieving energy-saving effects. 2. It can effectively block solar heat, thereby reducing the load on the air conditioning system, improving fuel efficiency, alleviating the load on the car engine, preventing fading and aging of items inside the car, and protecting the owner's skin from harmful UV rays. It also helps maintain eye comfort and reduces accidents caused by glare. Due to the one-way transparency of solar film, it can also serve the purpose of protecting personal privacy.
Don't rush to install the ETC after window tinting – let me share my experience. Newly applied window film needs time to dry completely; generally, you should wait at least 24 hours before safely installing the ETC device. Last time, I installed the ETC just half a day after tinting, and bubbles started forming in the film! This happens because the film is still curing, and the adhesive isn't fully stable yet. When the ETC tag is applied, any remaining moisture trapped in the film can cause shifting or damage. In warm weather, drying may be faster, but in cold conditions, wait at least 48 hours. Before installing the ETC, clean the glass thoroughly with alcohol to ensure it's dust-free. If you're in a hurry, consider using a temporary onboard card as a workaround. The waiting period isn't fixed—always check the tint film packaging instructions or consult a professional installer. Otherwise, the device may detach or malfunction at toll booths, causing major headaches. Bottom line: Be patient and don't take risks!
