<b>Installation Steps:</b><br/><br/> 1. Measure the surface and cut the film. Leave an extra inch margin each side for an easy adjustment. <br/>2. Clean the target surface thoroughly and make sure the surface is clean enough without any dust. <br/>3. Use two pieces of tape to stick on the corners of the film to gently peel off the transparent protective film before installation. (Very Important) <br/>4. Spray a lot of soapy water both on the adhesive side of the film and the window, then install the window film onto the window. <br/>5. Use the scraper to squeeze the film back and forth to make sure that the bubbles and water have been totally removed. <br/>6. Trim off the margins and enjoy your work<br/><br/> Of course, you can also go to YouTube to see how others have applied the window film. We suggest that you cut a small piece and try to paste it.
