Well, I went and did it. I took my car to EVS Motors for window tinting. The results look great, although they didn't at first. The film seemed wavy and looking through it was like looking through Coke bottle glass. I questioned the staff about this quite sternly. They reassured me that it took a few days for water under the film to dry and the film to cure. Three days later, my windows looked great and they looked even better after I cleaned them for the first time since tinting. Oh, and as I had anticipated, 75% Photosync on the front windshield is essentially clear.
