Very recently used Tint World on Burnet a little south of 183 (across from the Waterloo on Burnet Rd) to do front windows & sunroof on Audi Q5. The did a good job. Thinking about tinting the front windows on our high school son's car and will take it to those guys if I do.
I'm sure plenty of shops do a good job and I've used sunbusters in the distant past and they were good, but I've had two ppf, ceramic and tint jobs done by authentic details on two new cars and they are amazing. May not be the cheapest but I'd say they are one of if not the best auto detail and tint shops around.l, so I would at least give them a look. They are up in your area.
