What to Do About Bubbles in Rear Window Tint Film?

[OHope]

The solutions for bubbles in rear window tint film are as follows: 1. If bubbles appear shortly after applying the rear window film, and the bubbles usually contain white spots, it is due to improper handling of moisture between the film and the glass during application. The trapped moisture will evaporate and form small white bubbles the next day or over time, but the bubbles will not be large or numerous. This situation does not affect normal driving, and the bubbles will disappear once the moisture evaporates. 2. If bubbles appear several years after application and become increasingly numerous and larger, it may be due to the use of low-quality film. Over time, exposure to UV rays can cause the release of toxic gases like formaldehyde, leading to bubble formation. In such cases, the film should be replaced as it can harm health and should no longer be used. 3. Other reasons include poor film quality, such as aging adhesive layers, rough film structure, or easy detachment, which can cause bubbles or ripples under UV exposure. While this does not affect health, it impacts the car's appearance, so it is advisable to replace the film with a higher-quality one.
