Tinting FAQ & Laws

Why should I tint my car?

  • Window film prevents excessive heat build up and cools down the inside of the vehicle by reducing up to 60% of the sun's heat!
  • Protects you and your loved ones from by blocking out up to 99.5% of UVA & UVB Rays that can cause Skin Cancer and cause your vehicle's interior to fade and crack, having tinted windows is the equivalent of having SPF 300 sunscreen on all the time.
  • In the event of a collision, window film can keep shattered glass in place preventing flying glass from injuring vehicle occupants.
  • Window film can reduce the sun's blinding glare by as much as 94%.
  • Window Film darkens vehicle windows adding privacy and aids in preventing the interior of your vehicle from being viewed by potential thieves.

What are the laws on tinting?

The NZTA dictates what film percentages can be installed on vehicles in New Zealand, the law for all front drivers/passenger windows is 35% total VLT, on most cars we cannot simply put on a 35% film (Like the film found at Repco/Supercheap Auto) as your vehicles factory windows are very mildly tinted from 90% - 70% (lower % is darker) and the total VLT of the film and window would drop the percentage to 25% - 33% So we select from 39% and 47% films to get as close to 35% as we can using our VLT meter on a test sample applied to your window before we begin installation.  

Warrant of Fitness shops with VLT meters (VINZ, VTNZ) can fail your WOF on as little as 1% under 35% even though most VLT Meters are only accurate to within 2% and need their battery's charged regularly or they can misread your film by up to 20% (We have seen this many times in Dunedin from local WOF stations), so always seek a second opinion before removing your vehicles film, While most normal WOF shops will be fine with 30% to 35% we can install film under the legal VLT rating at your request after knowing the risks but we take no responsibility if your WOF is failed on windows tinted below legal limits.

How long does it take to tint the windows on my vehicle?

Vehicles vary from one to the next. The average install is about 3 - 4 hours for a normal sized car. Some factors that may play a part in the time involved are: What kind of vehicle it is. How many doors there are. If there are any unforeseen scenarios that come up (for example: if a rear deck lid needs to come out). If old tint removal is involved.


Why do I see watery bubbles? (right after install)

The moisture we use for install can remain between the film and windows for up to 2 to 3 weeks, sometimes longer in colder climates. Moisture or condensation comes in the forms of haziness and water bubbles or pockets. They clear up. The moisture simply evaporates. Never try to push around any of these water pockets, for this can create air pockets which don't go away on their own.


Does the tint go on the inside or outside of the windows?

All tint is installed on the inside of the vehicle windows. Sometimes a customer may see prepping being done on the outside. For example: the shrinking of the rear windshield.


What can I clean the windows with?

Always wait about a week to clean the windows after film install. Moisture that gets to the outside edges of freshly installed film can get sucked under the film and create bubbles.  We always recommend a clean microfiber cloth and water to clean all window films but If a metallic or ceramic film is installed, any window cleaning product can be used. If non-metallic is used, cleaners with ammonia cannot be used. Never use a cleaning cloth or pad that is abrasive.


Can I wash my car right after install?

Yes, since all the film is installed on the inside of the windows, the outside of the car being washed...or rain for that matter, will not create any problems. Just make sure the inside windows remain uncleaned for about a week.


Are the rear windshields tinted in one piece?

Yes, 99% of the vehicles that come through Auto Tint & Sound are heat shrunk via a prepping process and then installed in one piece on the rear windshields.


How long do I need to keep my windows up?

After install, the tinted windows will need to remain up for 48 hours.


My car is equipped with a feature that drops the window slightly when I open the door...will this cause a problem for tinting?

No, not at all. We, as well as most tint shops, are aware of this feature. It has been around for years. We know what to do so that the windows will be tinted in the full up position so that no gap will result when the doors are closed


What's with the dot-matrix pattern around my windows?

Dot-matrix is very common. It's the small black dot pattern that lines the outside of most rear windshields, and sometimes others as well. The thinner, more common dot-matrix patterns will look uneven when film is first installed, but should even out to create a "framed" look when dry


But what about the heavy, thick section of dot-matrix on my rear windshield?

This has a different solution. We don't tint up into the very heavy and thick sections of dot matrix because the tint will never lay even. Dot-matrix is a raised surface on the glass, with dots very close together. The better metallic films on the market today will not have the flexibility to lay evenly through the larger dot-matrix' surfaces. It tends to float and look cloudy and hazy.

The solutions we choose from are trimming the film around 1 cm into the large matrix trying to match the smaller area on the sides so it appears uniform from the outside, their is also a special black vinyl which resembles the outside black solid edges of windows that we can apply at an extra cost, The vinyl will remain solid black, never peel, and never haze up. It's truly the nicest, most appealing look for heavy dot-matrix rear windshields.


Does it cost extra to remove old film?

Yes, de-tinting takes a few hours to be done correctly and varies with the age and quality of the film. The most crucial part is taking film off the rear windshield of vehicles that are equipped with rear heating elements (defroster). There is a process to have this done safely to not ruin this important feature. Therefore, there is a charge that can be quoted when booking your appointment


Will my tint fade, bubble, or turn purple?

We only use the best films in the industry, we can provide all the warranty information in person. But for simplicity sake: The minimum warranty for our films is 5 years, most come with a Lifetime warranty against bubbling, peeling, fading, demetallizing, delaminating, and colour change!


Does window tint have to be dark to work?

It is a myth that window film must be dark to be effective, Window films come in different product types with all varying degrees of performance, and each product has several different light transmissions and heat rejection levels, all with the same properties of UV resistance of 99%.


After the window is tinted...I see little tiny bubbles scattered on the glass.  Will they go away?

The answer is yes and no.  Unfortunately, tint shops are not work areas that are sealed in a vacuum (vacuum-sealed: a space relatively empty of matter) so one will have tiny dust particles caught onto the film, we go to great lengths to minimize these dust partials, however as the film cures it will tighten up around these spots and they will become even smaller and less noticeable, even more so with a small rub with a finger nail to help press the tint around the dot.
