Volvo S90 wheel repair & painting: ₩800,000-₩1,800,000. Restored diamond-cut wheels with laser welding and powder coating.
Restoring the Volvo S90's Intricate Wheels
The Volvo S90, a premium sedan, boasts elegantly designed wheels. Specifically, the 20-inch diamond-cut finished wheels present a challenge for repair due to the minimal height difference between the painted surface and the cut lines. This makes any mistake during the restoration process difficult to rectify. In this case, the customer's S90 wheels suffered severe damage to their edges. Simple surface refinishing wouldn't suffice. Deep-seated damage affects the underlying aluminum structure, necessitating a precise three-stage process: welding, painting, and cutting, to restore the wheels to their original condition.
The Unique Challenges of S90 Wheel Restoration
Unlike standard wheels, the S90's wheels have a very shallow step (around 0.2mm) between the painted and cut surfaces. While this design enhances elegance, it significantly increases the margin for error during repair. Over-polishing or incorrect cutting depth can lead to the entire wheel needing a full powder coating. The damage on this particular S90 was characterized by severe edge scratches, indicating not just surface scuffs but actual gouges in the aluminum. Therefore, laser welding was essential to fill these depressions and restore the original shape.
The Three-Stage Repair Process: Welding, Painting, and Cutting
The restoration process involves several critical steps:
- Stage 1: Laser Welding the Damaged Area Aluminum filler material is precisely applied using a laser to the gouged sections. A crucial aspect of this stage is maintaining the wheel's balance. Uneven welding can cause vibrations during rotation. Including cooling time, this step takes approximately 1.5 hours.
- Stage 2: Side Black Painting & Powder Priming To ensure a seamless transition between the welded area and the original finish, the sides are painted black. This utilizes powder coating, not standard urethane paint. Powder coating involves electrostatically applying powdered coating material, which is then cured at high temperatures in an autoclave. This method results in a hardness exceeding 3H and superior impact resistance compared to conventional painting.
- Stage 3: Diamond Cutting & Powder Clear Coating Following the painting, the most critical step is the diamond cutting. This process uses a super-hard alloy burr to precisely shave the wheel's surface, restoring its dimension and luster. For the S90 wheels, accurately replicating the original cut pattern is paramount, requiring depth adjustments within a ±0.05mm tolerance. This stage alone takes about 3 hours. Finally, a UV-curable powder clear coat is applied to finish the process.
The entire process typically takes around 6 hours. However, if exceptional gloss is required on the welded areas, an additional 1-2 hours of polishing may be necessary. The cost for restoring 20-inch Volvo S90 wheels generally ranges from ₩800,000 to ₩1,800,000 in Korea, depending on the extent of the damage (surface vs. deep gouges vs. structural aluminum damage), the scope of the diamond cutting (partial vs. full), and the powder coating coverage. This specific vehicle required extensive edge repair and a full diamond cut re-application, placing it in the mid-to-high cost bracket.
Frequently Asked Questions
Q. How much does wheel repair cost for a Volvo S90?
In Korea, the cost for repairing and painting 20-inch Volvo S90 wheels typically ranges from ₩800,000 to ₩1,800,000. In the US, similar premium wheel repair services can range from $300 to $800 per wheel, depending on the damage and finish.
Q. Can curb rash be fully repaired on Volvo S90 wheels?
Yes, curb rash and even deeper gouges on Volvo S90 wheels can be fully repaired through processes like laser welding and precise refinishing. To maintain the repair, avoid harsh cleaning chemicals and ensure wheels are dried thoroughly after washing to prevent corrosion.
Q. Is wheel repair or replacement cheaper for a Volvo S90?
Wheel repair is significantly cheaper than full replacement for a Volvo S90, especially for models with complex diamond-cut or multi-stage finishes. Repair is ideal for cosmetic damage like curb rash or minor bends, preserving the original wheel's integrity and cost-effectiveness.
Q. How is wheel curb rash repaired on a Volvo S90?
Curb rash on a Volvo S90 wheel is repaired through a multi-step process: 1. The damaged area is meticulously cleaned and prepped. 2. For deeper gouges, laser welding fills the imperfections with aluminum. 3. The repaired section is then carefully ground and smoothed to match the original contour. 4. The wheel undergoes powder coating for durability and then precise diamond cutting to restore the original finish, followed by a protective clear coat.
Q. What is the difference between wheel refinishing and full replacement for a Volvo S90?
Wheel refinishing restores the original appearance and integrity of your existing Volvo S90 wheels, often involving repair of damage like curb rash and repainting or re-cutting the finish. Full replacement involves purchasing entirely new wheels, which is considerably more expensive and typically only necessary if the wheel is structurally compromised beyond repair.
