Hi Robert. Though we mostly live in NM, we have a home in Tucson as well. I've been using the Specialists near Auto Mall for years. They've been basically handling Formula 1 Pinnicle Ceremic Tint on several ofour cars, including 3 of our 4 BMWs, and will be doing replacemetn tint on my wifes recent car, a 2010 535xi bought in Albuquerque last month when she gets back to Tucson mid-January.
Rich and Luis have done all our work and they know tint for certain - at the least.
Regarding Clear Film paint protection, I can't speak to that done by The Specialists.
However, I have seen some here in NM that was crap or poorly installed. In 2006, I opted for Armor Coat
paint protection on my Cad DTS. I am very happy with it and am having it sprayed on my 2008 535i this week - car is already at the shop. Further, once my wife gets back home in February, we're having the front of her car done as well.
That Clear Film I've seen here was crap in that it didn't do a very good job protecting the paint. Now it may not be the same stuff that the guys in Tucson carry but the film I'm seen doesn't do anywhere near the job the Armor Coat does.
Just my opinion.
