Review on Gila Decorative Botanical Window Film - Static Cling, No Glue or Adhesive, DIY - 3ft x 6.5ft (36in x 78in), Frost Finish - Residential Use, 19.5 sq ft by Tonya Fisher

I installed it myself and love it! I would recommend watching the Gila video for instructions. I watched it several times because I had never done a project like this before. It was surprisingly easy! I used their set which was fine. But I would recommend having a proper cutting device like a utility knife as the little green one didn't work very well. If you run out of spray, simply add a drop of baby shampoo to the Gila bottle and top up with distilled water. I used distilled because I didn't want minerals from the tap water getting into the finished product. I believe the most important part of the installation process, after the window and film have been fully sprayed, is the time you spend using the yellow hard card to push out any air bubbles. I spent about 20 minutes sliding the card, wrapped in a lint-free cloth, to the very edges of the foil. I even had a paint smudge on the window that I somehow missed and it was very easy to fix. I simply lifted the film, removed the stain, repainted the window and film, and washed again. Presto. My window dimensions were about 27 x 34 so it's not hard to do it yourself. If they are larger, I would recommend hiring an assistant to help.
