Genesis GV70 Window Tinting Review: Rainbow i90 Re-application

Daegu Front Window Tinting: The Right Choice for Vehicles Needing Re-application

If your car's existing window tint is peeling or discolored, re-application is essential. This case study details how a Genesis GV70 received a new tint using Rainbow i90 film at a specialized Daegu Dong-gu shop, focusing on achieving both heat rejection and clear visibility. The process involved completely removing the old film before applying the new, highlighting why re-application is necessary and how it was performed.

The cost of front window tinting varies based on the vehicle model and the chosen film's grade. Generally, for a domestic mid-size sedan, partial tinting (front and side windows only) ranges from 400,000 to 800,000 Korean Won, while full tinting (including the rear window) costs between 700,000 and 1,500,000 Korean Won. Imported cars or large SUVs may incur higher costs. The typical installation time is 2-4 hours, often allowing for same-day completion and vehicle return.

The Importance of Re-application Starting with Old Film Removal

The crucial first step in any re-application is the thorough removal of the existing window film. Upon arrival, any peeling film, adhesive residue on the glass, or UV-damaged areas are meticulously cleaned. Neglecting this stage can lead to lifting or bubbling issues with the new film.

Specialized solutions are used to dissolve remaining adhesive and remove even microscopic dust particles, a process referred to as "delicate pre-cleaning." The quality of this initial step significantly determines the final finish.

Enhancing Perfection with Heat-Forming Technology

The Genesis GV70 features a design with many curves, making a clean installation challenging with simple application. Heat-forming technology is employed, where the film is heated to 45-60 degrees Celsius and precisely molded to the vehicle's contours. The Rainbow i90 film, a premium product, uses materials conducive to heat-forming, ensuring a natural, bubble-free fit around edges. Tinting the front windshield, side windows, and triangular quarter glass requires professional skill to adjust heat-forming intensity for each specific area.

Section-Specific Installation: Front vs. Side Windows

Front window tinting encompasses the windshield, left and right side windows, and the rear triangular glass (pillar areas). Each section has different curvature and angles of sun exposure during driving.

The windshield has the gentlest curve and demands high visibility. Rainbow i90 offers excellent heat rejection (99% IR rejection) while minimizing visible light loss, meaning it effectively blocks sunlight without making the view appear dark.

Side windows have more pronounced curves, making heat-forming the most intricate part. They are prone to wrinkles or lifting after cooling, requiring gradual cooling and air gun techniques to remove air bubbles. This delicate process alone can take 10-15 minutes per window.

Preventing Contamination and Final Inspection

The most common cause of installation failure is "dust contamination." Even a 1mm speck of dust trapped between the film and glass can create a bubble, eventually leading to lifting. To prevent this, the work area is isolated, and a water spray is used to settle airborne dust before application.

The final inspection checks for ① bubbles across the entire glass surface, ② lifting at the edges, ③ color consistency, and ④ color matching with any existing adjacent tint. For the GV70, ensuring the new front tint seamlessly matched the previously applied side tints was crucial for a cohesive look.
