When adding window tint, most people want dark tint with the idea to block heat, stop Glare etc... Then driving at night suddenly you realize it's hard to see out of your windows and your uncomfortable driving. Hard to see when maneuvering, people in crosswalks... (old school technology)
Today's high end Tints do the work of Blocking Heat, Reducing Glare, with the Highest Visual Clarity without having to add darkness. Try driving at night with dark sunglasses on. (Don't do it, it's not safe)
We use 3M Crystalline film here at MasterShield for all the above reasons. Crystalline has film from Clear to 40%. (% numbers means the amount of light the film lets come through) Most cars we use 70% including windshields because it takes care of all the above concerns, Heat Blockage, Glare, UV Protection without being seen, or changing the look of your car. We are proud to offer 3M Crystalline films. 3M is the leader, and has always been known World Wide for Quality, Warranty, and 3M's attention to detail and support. 3M invented window tint way back in the 60's and now uses today's technology in manufacturing Crystalline.
This is basic information. Whichever film you decide to purchase, it needs to fill your needs not the installers. (higher end films like Crystalline are difficult to install) When it comes to price and tint, you will get what you pay for. Window Tint is not just tint anymore. When 3M made Crystalline with 220 layers to reduce Heat, UV, and Glare, and help secure your car's windows, they did it for those reasons. The end result choice is yours of the type and manufacture of the film on your windows, and it's exactly what you wanted, works the hardest for you and will look the best the whole time you own it.
MasterShield is proud to use 3M film, we install it with the idea, no one knows it's on your car.
