Can You Roll Down the Windows After Leaving the Car Film in the Sun for a Day?

[DelHope]

You should not roll down the windows after leaving the car film in the sun for a day. Here are the reasons why: 1. The car film requires time to dry out residual moisture: Even professional installers can only remove up to 80% of the water after application, leaving the rest to evaporate naturally. If there are only a few bubbles left, exposing the film to sunlight can help speed up moisture evaporation. Otherwise, lingering moisture may interfere with driving visibility in the long run, so letting it dry in the shade is not reliable. 2. The glass is usually tight immediately after film installation: Rolling the windows up and down can easily cause the edges of the film to curl, peel, or shift due to insufficient adhesion, potentially damaging the newly applied film. 3. Additional benefits of car window film: It helps protect both passengers and the car's interior from UV damage. By physically reflecting sunlight, it reduces the interior temperature, lessens the need for air conditioning, and thereby improves fuel efficiency, saving costs.
