Features: 1. Super thermal insulation, driving during the day and night, with still clear visibility. 2. Protect the car windows to prevent damage to the glass surface. 3. Installation position: front and rear windshields, windows, sunroof, etc. 4. Size 50 x 300 cm. 5. Installation instructions: 1. Measure the size, length, and width of the car glass by adding more than 3 centimeters each to avoid non-standard glass leakage during installation. 2. Clean windows are crucial for successful installation, so please keep the windows or glass clean. 3. Remove the transparent backing from the film. Use a spray bottle to cover the entire surface of the film with soapy water. This helps prevent film entanglement and adhesion. 4. Pick up your film and apply it to the window (make sure you have removed it before applying it to the glass). The soap solution on the film and glass allows you to slide it into the correct position. 5. Then repeat the scraper process, using the scraper to push any remaining moisture or bubbles onto the edge of the window. It's much easier than wall decals, no problem for you! Step 6 Finally, dry the window with a tissue, then frame it, being careful not to lift the film at the edges or corners.
