I used Cactus Window Tint for a clear bra on my BMW 1M. I did the full front, side skirts, and rear fenders. These guys are all around amazing. Really nice people, superior customer service, and their work is perfect. I'm the kind of customer that these places generally do not like because I'm OCD about my car. I will find any slight imperfection. Hell, I refuse free car washes at the BMW dealer because I don't want them touching my car (it's black...swirls marks....). These guys definitely live up to their Yelp reviews.
I had looked around for quite some time as clear bras are not cheap. Down the street from them is the Cars Guys of Scottsdale whom I've used before, but their price was way more expensive and the cars they had done weren't as good as the examples I saw from Cactus Window Tint.
Couldn't be happier....
