Auto-indexing windows are a frequently used term in car tinting business. Some new cars like Mustangs, Corvettes and Chevrolet have auto indexing windows and if you’re applying window tint yourself you need to take it into account. Such auto adjusting windows can ruin your newly applied tinting film so make sure to educate yourself on how to properly apply tint to such cars.
Auto indexing windows are basically driver and passenger side windows that automatically roll down when you open your doors, and roll back up when you close them to create a water-tight seal. When you tint the windows on your car they are supposed to stay up for at least two days so it doesn’t ruin the tinting film.
Unless you don’t need to drive your car for a few days after tinting, there’s a few tricks you can use. One such trick for Corvette for example is to flip the latch mechanism to trick the window going up fully. A car tinting business will very likely know the exact process required to make sure your windows don’t auto-index so be sure to consult with them beforehand.
It’s just one of the reasons why you may want to think about leaving window tinting to professionals. While it may cost a bit more you can ensure it’ll be done professionally by people who are experienced with the process.
