Hi, I just tinted my ride a month ago with 3M Crystaline70 at a shop which is a distributor of 3M and I can assure you good service and most important good workmanship at this place.

FYI, I did the same as what u doing now, search for some recommendation and review for tinting film, and came to know to know someone that did his tinted at the same place. Visited a few places, and end-up tint with this shop...
The owner himself and his brother will do the tinting job themselves.....

so if you interested, let me know, will PM you the address and u pay them a visit and talk to the owner himself, no obligation.... proceed only if you are satisfy after talking to the owner ok

Yes Crystalline70 is not smart tag friendly, but there is a work around to solve the problem, no worry...

alternatively, you can tint the top part of the front windscreen with another type of solar film which is smart tag friendly and darker in color....

Yes, 3M do have security tint
