Hey Franco , I get all my tint right here in Longwood:
Window Tinting Automotive Residential Commercial Safety Central Florida
They are a bit more expensive, but their cuts are utterly perfect. Don't quote me, but I think the Lamborghini/Bentley dealership up the street also goes there.
Why choose them? They also do whole office buildings.
I jumped on the brand new 80% llumar ceramic tint as soon as it hit market. You can't tell it's there (including the whole windscreen) , but it cuts 99% UV and still has 30% heat rejection! They will gladly do a double 15% all around if that's what you really want (they did it to my brother's vehicle no questions asked)
Tell em you were recommended by that guy with the blacked out smart.
