Avoid rough, uneven, or frosted glass. 2. Uses electrostatic technology, no glue needed. Just spray enough water on the glass surface before applying. If it doesn't stick, add more water. 3. Remember to remove the backing film before use, or it won't adhere properly. 4. Pay attention to the front and back sides; ensure the back (smooth side) is applied to the glass for proper adhesion.
