Where are the 5 stickers that make the backing easy to remove from the film?
After peeling off the outermost plastic seal, you will find the EASY PEEL OFF sticker sheet between the instruction sheet and the window film roll. No more worries about the backing being difficult to remove.
How to remove the air bubbles?
Bubbles can be easily removed with a squeegee, and we have an installation kit for sale, which includes a felt squeegee, detachable knife & 1 extra blade and a 100ml spray bottle.
Why does the film come off after a while?
Please check that you have removed the backing, sprayed plenty of water on both the window glass and the window film and scraped out any excess air bubbles and water.
