Hyundai Grandeur IG Window Tinting Review — Cost & Results

Why Reapply Window Tint on Your Hyundai Grandeur IG?

Car owners sometimes face issues with their existing window tint, and the owner of this Hyundai Grandeur IG was no exception. After about three years, the original tint film began to show signs of wear: discoloration and a noticeable decrease in heat rejection. While the tint might look acceptable from a distance, over time, films can fade, often developing a purplish hue. This degradation significantly impacts the tint's primary function – blocking heat. Consequently, the car's interior can become uncomfortably hot, especially during warmer months. Furthermore, faded tint can compromise privacy, making the vehicle's interior more visible from the outside. This situation often necessitates a reapplication, highlighting the importance of choosing quality tinting materials from the start to avoid the expense of a double investment.

The Window Tinting Installation Process

Before any new tint is applied to a Hyundai Grandeur IG, a crucial step is 'vehicle protection' or 'body protection.' This involves carefully applying protective film or tape to both the exterior and interior of the car. The exterior protection guards against minor scratches on the paintwork during the installation. Inside, it's even more critical. Tinting solutions and chemicals can potentially damage leather seats, dashboards, and door panels, causing discoloration or staining. They can also seep into electronic components like switches and speakers, leading to malfunctions. While this preparation step might seem time-consuming, meticulous application is vital to minimize these risks.

Once the vehicle is protected, the old tint film is removed. This is typically done using high-temperature steam to soften the adhesive, ensuring that minimal residue or glue is left on the glass. The removed film from this Grandeur IG was visibly purplish, a clear indicator that its heat-blocking capabilities had diminished. For this vehicle, the chosen film was Rainbow V90, known for its impressive specifications: 99% UV rejection, over 90% infrared (IR) rejection, a total solar energy rejection (TSER) of 73%, and a visible light transmission (VLT) of 30% for the front windshield and 12% for the side and rear windows. These figures suggest a significant improvement in comfort and protection compared to the degraded original tint.

Before & After: The Impact of Quality Window Tint

The transformation after applying the new window tint to the Hyundai Grandeur IG is substantial. The most immediate benefit is the enhanced heat rejection, creating a cooler and more comfortable cabin environment. The 99% UV protection is crucial for safeguarding the car's interior from sun damage and fading, as well as protecting occupants' skin. The improved TSER of 73% means less solar energy penetrates the glass, further contributing to a cooler interior and potentially reducing the need for air conditioning, which can improve fuel efficiency. The chosen VLT levels provide a good balance between visibility for the driver and privacy for the occupants. Maintaining the new tint is straightforward: avoid washing the windows for a few days after installation to allow the film to cure properly, and use ammonia-free cleaners for regular cleaning.
