The wrong window film will ruin the AM. I know because I did it. I had a shop tint the windows and he only had one style of film- Metallic. They were dark brown. So the next week I got to pay another guy to tear off the original metallic tint film and then install the new Ceramic style tint film- dark brown. The side windows still are the metallic film and the rear window is now made from the Ceramic stuff. They look the same to me. But the radio came right back to life after switching to the ceramic. So the money I saved by going to LA to get the windows tinted I got to spend having the rear window re done. By the way, I watched him remove the old film- You need to know what you are doing. All sorts of fancy tools to get the old film off.
Bottom line, If you tint your windows, and I suggest you do- use the
ceramic style tint film.
