Genesis G80 Wheel Damage: How to Restore It?

Finding scratches on your wheels shortly after getting a new car can be frustrating. For luxury vehicles like the Genesis G80, replacing damaged wheels can be very expensive, leading many owners to ask, "Can they be repaired?" Fortunately, most wheel damage can be effectively restored through painting or cutting. This review details the diamond cutting wheel repair process for a Genesis G80 at a Korean shop, covering the steps, cost, and results.

Sandblasting vs. Diamond Cutting: What's the Difference?

Wheel repair typically involves two main methods: sandblasting (abrasive blasting) and diamond cutting. Sandblasting prepares the surface for a new paint job by removing old paint and imperfections. Diamond cutting, on the other hand, uses precision machinery to shave off a microscopic layer of the wheel's alloy surface, restoring its original polished finish.

Diamond cutting is ideal for wheels with a machined or polished face, like the G80's. It precisely recreates the factory look by carefully cutting into the metal. While it requires advanced equipment, it can be cost-effective for minor damage like curb rash. The cost for diamond cutting typically ranges from ₩70,000 to ₩100,000 per wheel (approximately $55-$75 USD), depending on the extent of the damage and the wheel's material. Sandblasting is also in a similar price range but is primarily for wheels that will be repainted entirely.

Genesis G80 Diamond Cutting Repair Process

The vehicle in this review was a 2023 Genesis G80. The owner brought it in because of a scratch on the front passenger-side wheel sustained during parking. Since the damage was superficial, diamond cutting was a suitable repair method.

How it works:

1. Tire Removal & Cleaning: The tire is first completely removed from the wheel. The wheel surface is then cleaned using an abrasive method to remove brake dust, dirt, and any remaining damaged paint.
2. Detailed Washing: The wheel undergoes both high-pressure washing and manual cleaning to ensure all microscopic particles are removed. This step is crucial to prevent imperfections during the cutting process.
3. Diamond Cutting: A specialized CNC machine precisely shaves off a thin layer (around 0.1mm) of the wheel's surface. This process restores the original machined finish and shine.
4. Clear Coat Application: Finally, a UV-resistant clear coat is applied to protect the newly cut surface from oxidation and environmental damage.

This repair was straightforward due to the shallow nature of the scratch. The entire process, including tire removal, cutting, and clear coat application, took approximately 2-3 hours. The wheel was ready for reinstallation the same day.

Wheel Diamond Cutting Cost for Genesis G80

The cost for the wheel repair on this Genesis G80 was ₩70,000 per wheel (excluding VAT), which is about $55 USD. Additional rubber valve stems can be purchased for ₩7,500 each if needed, but they were not required in this case as the original was in good condition.
