Genesis G90 Wheel Repair & Painting Review — Restored to Perfecti

Genesis G90 Sputtering Wheel Restoration: When Premium Needs Perfection

The Genesis G90 stands as a symbol of luxury, demanding impeccable exterior maintenance. Its signature sputtering wheels, often called "plate wheels," boast a captivating gloss and depth, but damage can complicate restoration. This review details a real-world G90 wheel repair and hyper black powder coating project at Today's Car Cheonan, demonstrating the meticulous process required to bring these premium wheels back to their original splendor. For Genesis vehicles, maintaining the high original quality standards is paramount, especially for wheel restoration.

Why G90 Sputtering Wheels Are Challenging to Restore

G90's sputtering wheels feature intricate surface patterns that create a dynamic, three-dimensional effect when light hits them. This complexity, however, makes them prone to collecting dust and significantly impacts the vehicle's overall aesthetic when damaged. In this specific case, the wheels had previously undergone powder coating by another shop, and that coating was beginning to peel. This necessitated an essential additional step: stripping the old coating.

Skipping the stripping process means the new paint layer will only adhere to the old, compromised coating, drastically reducing durability. For a premium vehicle like the G90, a foundation built from scratch ensures longevity. While stripping incurred extra costs, the customer approved, allowing for a proper, high-quality restoration.

The 3-Step G90 Wheel Restoration Process: Sandblasting is Key

The crucial first step in restoring Genesis G90 wheels is sandblasting. This process uses high-pressure air and abrasive media (fine sand) to remove the existing coating and simultaneously prepare the wheel surface. This creates a "rough" profile, ensuring the new paint adheres firmly.

Following sandblasting, thorough cleaning with detergents and specialized chemicals, along with degreasing, is performed. Despite these measures, minor imperfections like "cratering" can sometimes occur due to microscopic surface impurities. This is a critical detail to address for wheels where gloss and finish, like those on the Genesis G90, are paramount.

Powder Coating in 3 Stages: Base, Color, and Clear

The actual painting process utilizes powder coating, executed in three distinct stages to perfectly replicate the G90's hyper black finish.

1. Base Coat - Black Powder Coating: The first layer is applied and then cured in a 180°C oven for 15 minutes. This thermal process chemically bonds the paint to the wheel, virtually eliminating the risk of future peeling.

2. Mid Coat - Hyper Sputtering Color Application: This stage precisely recreates the original sputtering wheel color of the G90. After undergoing the same heat curing process, the finish closely matches the factory appearance.

3. Top Coat - Acrylic Clear Coating: The final layer is a transparent clear coat, vital for the wheel's overall durability and appearance. Today's Car Cheonan uses the same acrylic powder clear coat used in original Genesis wheel production. This protective layer shields the paint from UV rays, acid rain, and harsh tire cleaning chemicals, ensuring a lifespan of approximately 3 to 5 years.

Genesis G90 Wheel Restoration Cost and Time

The typical cost for Genesis G90 sputtering wheel restoration ranges from ₩350,000 to ₩550,000 per wheel (approximately ₩1.4M to ₩2.2M for a set of four). However, as seen in this case, if existing paint removal (stripping) is necessary, expect an additional cost of around ₩50,000 to ₩100,000 per wheel. The final price can vary based on the extent of wheel damage, the original paint condition, and regional pricing differences.
