Updated: I'm a repeat customer of Cactus Tinting for my 2017 Chevy SS and my previous 2013 Volkswagen. The shop owner 'Rick' does, in fact, go out of his way to provide excellent customer service.
During my recent visit, there were a couple of missteps in communications, but the owner made it right by discounting the bill. They carry the top-of-the-line materials, and they don't try to top-down sell anything. Even so, I opted for the premium quality 3M 'Crystalline' tint and the 'SunTek' protective films. This stuff is pricey, but I think it's worth it, especially in our Arizona heat.
The SunTek matte clear material installed on my car roof have some production roller marks (stripes) in a relatively narrow section of the film itself, and not from the way it was applied. This is the same material typically referred to as 'invisible bra.' Hopefully, it will blend after some time in the sun.
'Cactus Tinting' is conveniently located on Raintree Rd. in Scottsdale and the facility is neat and clean with a clean workshop. In particular, I like Rick's work ethic so I wouldn't hesitate to recommend his business to any of my friends.
