I'm always tinkering with my car, and I've seen plenty of cases where the rear window film bubbles up, mainly due to trapped air or moisture during installation. For small bubbles, you can use a credit card or a specialized squeegee to gently push from the edge toward the center of the bubble, gradually pressing out the air—just be careful not to press too hard to avoid scratching the film. If the bubble is large and stubborn, consider redoing the film, as it can blur your vision while driving, which isn't safe. To prevent this next time: opt for high-quality film, like ceramic film, which is more heat-resistant; avoid rolling down the windows for 48 hours after installation to let the film dry completely. Park in shaded areas to avoid direct sunlight, as high temperatures can cause the film to expand and bubble. When cleaning, use a slightly damp cloth and avoid alcohol-based products to protect the film and extend its lifespan. For those who aren't handy, it's best to leave it to professional tint shops—saves time and effort.
