I hired a handy person to install Gila privacy window film on my patio door windows and he was really impressed with both the solution and the cutting tool.
If you鈥檙e installing on patio door windows, my advice would be to buy multiple kits or else you鈥檒l run out of solution. Follow the instructions and douse the film and windows in lots of solution for the best adherence. Had my film up for almost a month now and it鈥檚 great. FYI, the price of buying just the solution was more expensive, go figure.
