Specialized Wheel Services for Luxury Imports

The featured workshop in Gangnam is a dedicated facility focusing on high-end import car wheel repair, including brands like BMW, Porsche, and Mercedes-Benz.

For severe damage, such as deep gouges on the rim edge, structural repair through welding is crucial before cosmetic refinishing can achieve a lasting result.

The BMW XM Wheel Repair Process: From Damage to Perfection

The repair process for the BMW XM's damaged wheel involved several critical stages:

1. Damage Assessment and Cleaning: The initial step involved a thorough inspection of the wheel to determine the extent of the damage. The 22-inch wheel had noticeable scratches along the rim edge, affecting both the machined aluminum face and the deeper sections of the lip. A comprehensive cleaning was performed to prepare the surface for repair.
2. Aluminum Welding for Structural Repair: Deep scratches and gouges on the wheel's edge require more than just cosmetic filler. Aluminum laser welding is employed to rebuild the damaged material, ensuring the wheel's structural integrity. This is vital, as simple putty or filler would not withstand the stresses of driving and could lead to vibrations or further damage. After welding, the repaired area is meticulously machined and smoothed to be perfectly level with the original surface. This ensures a uniform finish after painting. For enhanced durability and resistance to future minor damage, the repaired aluminum surface is finished with a composite material rated at 3H hardness or higher.
3. Powder Coating for Glossy Black Finish: The wheel was refinished in its original glossy black color using the powder coating method. This process involves applying electrostatically charged powder paint to the wheel, which is then cured in an industrial oven. Powder coating offers superior durability and a harder finish compared to traditional liquid paint.
4. Curing and Final Polishing: A critical aspect of powder coating is the curing process. The paint requires a minimum of 48 hours of natural curing time after the oven process to reach its maximum hardness and durability. While the actual welding and painting might take around 6 hours, the full 48-hour cure is essential before the wheel can be considered ready for pickup or reinstallation. Following the cure, a final polishing step is performed to achieve a high-gloss finish that closely matches the original factory appearance. The powder coating process often results in a deeper, richer black hue than standard paint.

Cost of BMW XM Wheel Repair

The cost for repairing a large, high-end import wheel like the BMW XM's, especially when welding is required, typically ranges from 600,000 to 900,000 Korean Won per wheel. Wheels with only minor cosmetic damage that do not require welding may cost between 300,000 and 500,000 Korean Won.
