Installation & Care

1. Do not roll down the windows for 48 hours after film installation.
2. Do not clean the window or use the defrosting function for 7 days after the film is installed to ensure complete adhesion to the glass.
3. Avoid using pads or cleaners containing abrasives or industrial glass cleaners.
4. Do not use ammonia- or alcohol-based cleaners when cleaning the window.
5. When cleaning the window, gently wipe it with a dry towel and lukewarm water.
6. Avoid attaching stickers or adhesive tapes to the coated surface.

 

Drying Period Reminder: Please be advised that between 4 and 10 weeks after installation, temporary visual distortions, such as blurring or water droplet-shaped marks, may occur as the film completes its drying process. This is a normal occurrence and will not impact the long-term performance or quality of the product. These effects will resolve once the film has fully adhered to the glass.
