TeckWrap Zenith30 Nano Ceramic Window Tint Film (C30-2mil)

Zenith30 unless you have a reason. At 30 percent visible light transmission it reads as a proper tint from outside, gives real privacy and glare control, and still leaves enough light for shoulder checks and reversing after dark. Zenith15 closes the rear cabin down properly for cargo and passengers. Zenith70 is for windshields and front sides where visibility is the priority.

Where the law allows it, and Zenith70 is the film for it. At 75 percent transmission the glass stays visually open while still cutting 88 percent of infrared and 45 percent of total solar energy. The proposition is not privacy, it is a windshield that stops radiating heat at your hands and face.

Almost never. That is mounting solution still evaporating through the film, and it clears on its own. Give it a few days in warm weather and up to a few weeks in cold. Cure time is 24 hours minimum above 15°C (59°F) before you touch it.

Not for at least 24 hours, and longer in cold weather. Dropping a window before the adhesive has set drags the film edge down into the door and peels it. This is the single most common self inflicted failure on a fresh tint job.

Not on these constructions. Purple fade and bubbling are dyed film failures, where the dye breaks down and the adhesive goes with it. Sputtered metal and nano ceramic layers hold color and performance instead of drifting. Zenith carries an 8 year warranty, Ionix 5 years.

No. The construction is entirely non metallic, which is the reason to choose it on rear glass carrying defroster grids and embedded antennas. Nothing in the film interferes with signal.

It is the right thickness for the job. Ceramic performance comes from the particle layer, not from bulk, and 2 mil handles installation and daily use with an 8 year warranty behind it. Extra thickness on a window film buys you nothing except a harder install.

No, and this is the most expensive misunderstanding in tinting. Darkness is privacy and glare. Heat rejection is construction. Zenith70 at 75 percent visible light transmission still rejects 88 percent of infrared and 45 percent of total solar energy, while a cheap dark dyed film can reject far less heat than that while making the car harder to see out of. Buy the construction, then choose the shade.

TSER, not IR rejection. Infrared rejection measures one slice of the spectrum and is the number films are marketed on because it reads highest. Total Solar Energy Rejected accounts for the whole solar load, which is what you feel. When a film advertises a huge IR number and never prints its TSER, that is the answer.

Because you drive at night. High internal reflectance turns the inside of the glass into a mirror after dark and throws your own dashboard back at you. Both Zenith and Ionix hold internal reflectance to about 6 percent, which is low for the category and is a comfort figure nobody advertises.

Check the net figure, not the film figure. Your glass already blocks light before any film goes on, so a 35 percent film on factory glass lands well below 35 percent measured. That is how people pass at the shop and fail at the roadside. Front, rear and windshield limits differ by state and country, so confirm locally before ordering.
