Gila Window Film Application Tool Kit - DIY Window Tinting Kit for Heat & UV Protection - Perfect for Home, Office, and Car Windows

I bought this kit because I didn't want mess up when mixing my own spray solution. I used the spray very liberally and it was enough for four windows. After I ran out of the spray solution I mixed my own using a few drops of Dawn dish detergent in a spray bottle and it worked just as well. I didn't care for the included squeegee tool or razor and ended up using a squeegee I had with felt on one side and hard plastic on the other. I also preferred using a cheap extendable razor I had laying around. In the end I think you would be better off purchasing a another window tint installation kit that comes with different tools and then mixing your own spray solution. I gave it three stars because it does work fine, but I think there are better options out there.
