I got my car tinted last week. They put a sticker over my window controls that says not to touch the windows for 3-5 days. They also said I needed to let this specific tint "cure" to the windows for 2-3 weeks. No washing with any ammonia based products. I now can't get fast food as easily but at least I won't be as much of a fat ***.
I got the "Ultimate" as seen here.
