I have used Flying Window Tinters in Longwood since 2001 on 4 cars, 3 Bimmers. The price keeps going up and they are the most expensive from Ocala to Tampa to Orlando, but I'm not sure I want to try anybody else. The same guy has been doing the cars since at least 2005 when I had my second car done, so he has plenty of experience. They use Formula One which is made by Llumar but higher end and only approved shops can install it as opposed to anybody can install Llumar.
There is a fake Flying Window Tint on Semoran though and that's not the place. I might try 3M this time at a good looking shop in Winter Haven I believe.
