SW 80% VLT Nano Ceramic Car Front Window Film, 99% Anti UV Heat Insulation Sun Blocking Solar Window Tint, Transparent Blue, 20Inch X 10Feet

Makes a significant difference
This product is amazing in regard to cutting down the heat without compromising vision. I put this on my motorhome to cut down on the intense heat when we drive. And it worked quite nicely. With the remaining roll I attempted to put on my car windows but due to my windows being slightly curved would not stick without a bunch of wrinkles. This is its only downfall as applying it can be difficult and creases extremely easily. But if you can get it on without creases then it’s literally a game changer. Especially if ur in the desert like I am.

Higher temperatures after installing this film.
I out this in my kitchen sliding door one section of the glass on the outside to deflect the heat. Temperature reading is higher in that section than other 3 sections. I would not recommend this film.

Use a lot of water with a dash of Dawn!
I used it on my home windows, it was enough to do 3 windows 34″ wide x 72″ but because I had to cut it for the top window then another piece for the bottom window six times. The first piece turned out to be the worst and the sixth piece was the best lol. The first one I cut to match the window and because it was super hot outside the water on the window was drying before I could get the film separated, so I kept having to wet the window. The most difficult part was getting the film to separate and I wish I would’ve had a helper but I did it alone. The film when you are pulling the back off it will want to stick to itself and when that happens just use a water bottle with the soapy solution and spray it alot as you pull the back off or even in the area where it gets stuck on itself. I advice not cutting it to fit before hand but rather keep an extra inch on all sides and use an exacto knife and trim it after you get it flat on the window (I used a wide squeegee made for this purpose that I bought separately) By the time I got to the last window I figured out how to get the film off the back by using electrical tape lol (I am not one to read all the directions which suggests using tape) and I also began putting water on the back as I took the film off and then put it on the window vs pulling it off from under it while trying to put it on the window as I did the first time and found out real quick it was too difficult. Also the tape came in handy to hold the film on the corner of the window while I smooth it out.

Works!
This ceramic film works. I’m not getting paid or asked to do this review just doing it because reviews help me when I purchase. These are my pictures from the tests I did. I will be updating with some new pictures when I can find a day with same temp as my no film picture. As you can see it was 90 degrees outside when I took the after picture at the same time of day which happened to be the following day just that it was 15 degrees hotter. Even with that, you can see that the film brought the temperature on the window sill way down and would be even lower if it was only 75 degrees out. I saw another post on here that said the film didn’t work because they took the temp of the window and it was hotter, however, that shows the film is working because it is containing the radiant heat in the ceramic particles in the film and not letting them go through the window to the inside of your house. My experiment shows the window sill does not heat up as much as without film, proving that it works at keeping the radiant heat from transferring inside your home. As far as installing it. Its a pain and my work does not look super professional at all but it does the job. I will post more pics later and hope this helps someone.
