Kia Sorento MQ4 Window Tinting Review: Royal Series 901 Upgrade

Kia Sorento MQ4: Time for a Window Tint Refresh

Even a well-maintained Kia Sorento MQ4 shows its age, and for one owner, the signs were in the window tint. After four years, the original film, applied via a promotional coupon, began to fade and its sun-blocking capabilities diminished significantly during the summer months. Simple cleaning couldn't restore its performance, prompting a decision for a full re-tint. Seeking a noticeable upgrade, the owner chose the premium Royal Series 901 window film, hoping it would surpass the limitations of the previous installation. This review details the process and the satisfying results.

Expert Removal and Meticulous Installation

The first crucial step was the removal of the old window film. This isn't just about peeling off the tint; a clean removal is essential for a flawless finish with the new film. After four years of UV exposure, the adhesive from the previous film, a LUMA HK on the front and LUMA GG on the sides, had bonded strongly to the glass. The detailing team employed heat-based removal techniques. For the front windshield, the film was pre-removed externally due to the nature of its adhesive, followed by a painstaking process to eliminate any residual glue. The side windows were treated with a similar careful, heat-assisted removal.

A particularly noteworthy aspect was the handling of the rear defroster lines. Removing tint from a rear windshield with integrated heating elements requires extreme caution to avoid damage. The team utilized a steam-based, low-temperature removal method, ensuring the delicate heating elements were perfectly preserved while the film was detached. This level of precision highlights the difference between a professional, experienced tint shop and a less specialized one.

Applying the Royal Series 901 Premium Film

Once the glass was stripped bare, it was thoroughly cleaned with a specialized solution to eliminate any microscopic dust or residue. This preparation phase, critical for bubble-free adhesion, accounts for about 20-30% of the total installation time. The Royal Series 901 is a high-end hybrid film, offering superior clarity and color depth compared to standard metallic films, with an added benefit of minimized electronic interference.

For this Sorento MQ4, the side windows were tinted to a 10% visible light transmission (VLT). This level provides significant privacy from the outside while maintaining clear visibility from the interior. The installation process involved:

1. Precise Film Cutting: The film is cut to match the exact shape of each window.
2. Application and Smoothing: The film is applied to the glass and meticulously smoothed to remove air bubbles and ensure a perfect fit.
3. Shaving: The edges of the film are precisely trimmed along the window's edge for a seamless, factory-like finish, preventing future issues with water or dirt ingress.
4. Rear Defroster Integration: Special care is taken when applying film over the rear defroster lines, using controlled heat and pressure to ensure adhesion without damaging the lines.

The front windshield installation followed, with the same attention to detail, ensuring optimal clarity and protection without compromising the driver's view.
