D-GROEE 20x150cm Car Window Sun Visor Strip Film Glossy DIY Car Front Windshield Protect Shade Sticker with Scraper

End result is a great sunshade! It adhered strongly and looks great. It was a 2 person job. After cleaning the outside of the windshield, I gently peeled about 3 inches of the membrane back exposing the very sticky adhesive side of the sun visor strip. I had the 2nd person unroll it and hold it tightly (I stood on one side of my van and she stood on the other side). As she gently pulled the strip toward her, I carefully lined up and placed about one inch of the sticky side onto the windshield. I placed the plastic tool (enclosed with the strip) against the film and drew it toward my wife about 1 inch at a time. I pressed it firmly against the windshield to make sure and eliminate bubbles. If there was a crease we would lift that part off and place it back down. As I worked across the windshield, some of the film went above the windshield onto the van roof but I kept going and took a razor blade and carefully removed that portion after I finished (the curved windshield caused that overlap). Again, the process went slow, firmly working bubbles out. After I finished, I carefully removed excess film with a new razor blade (BEING CAREFUL ONLY TO CUT FILM ON THE SURFACE OF THE WINDSHIELD BUT NOT WINDOW WEATHER STRIPPING OR PAINTED SURFACE). After I removed the excess film I then looked for (and found) more bubbles. I firmly worked them out as well. We both really like the finished job but it took a full hour to finish.
