BMW 7 Series G70 Wheel Repair Review - Like New Finish

Restoring the BMW 740i G70's Wheels to Perfection

The new BMW 740i G70 boasts a design of unparalleled sophistication. As a luxury sedan, maintaining its pristine condition is paramount. Wheel damage, such as scratches or curb rash, can significantly detract from the vehicle's overall elegance. Even a new car loses its premium appeal if its wheels are neglected.

The owner of this 740i sought professional wheel repair in Busan to address existing damage, aiming for a finish that would keep the car looking new for at least five years.

Assessing the Wheel Condition Before Repair

The 740i's wheels exhibited typical wear from daily driving, including deep scratches along the rim edge and a dulling of the surface finish. The original glossy black exterior had lost its luster, making the wheels appear generally lackluster.

The initial step in wheel repair involves a thorough diagnosis of the current state. Experts at the Busan branch systematically assessed the damage on each wheel to determine the most effective restoration method.

The Wheel Repair and Painting Process

Wheel repair is more than just a simple repaint. It begins with removing the existing coating and meticulously sanding down the damaged areas to achieve a smooth, uniform surface without compromising the wheel's original structure.

For the 740i's glossy black finish, restoring a high level of shine was crucial. After precise surface preparation, either powder coating or a two-component urethane paint was applied. These methods offer superior durability and a more consistent finish compared to standard spray painting.

Following application, a proper curing process is essential. Allowing at least 24 to 48 hours for natural drying ensures the paint fully hardens and achieves its intended durability. Rushing this stage can severely impact the final finish quality.

The Transformation: Wheels Like New

After the restoration, the 740i's wheels looked as if they had just come out of the box. The deep, glossy black finish was revived, and the rim scratches were completely gone, achieving a "like-new" shine.

For luxury brands like BMW, wheel condition is critical to the car's overall image. The elegant design and sophisticated lines of the 740i are fully realized only when the wheels are in perfect condition.

Cost and Time Involved

The cost for wheel repair on a large luxury sedan like the BMW 740i varies based on the vehicle, wheel size, and extent of damage. Typically, for 20-inch or larger wheels, the price ranges from 250,000 to 400,000 Korean Won per wheel. A full set of four wheels usually costs between 1,000,000 and 1,500,000 Korean Won.

This 740i owner opted for a full four-wheel restoration, which took approximately 5 to 7 days, including drying time. While same-day service isn't possible, options like loaner vehicles or pickup services can minimize inconvenience.

Maintaining Your Repaired Wheels

Wheel repair is the beginning of ongoing care. To preserve the newly painted finish, regular maintenance is key. Wash the wheels gently with a neutral detergent every 1-2 weeks to prevent brake dust buildup. Avoid harsh chemicals and high-pressure washers.

With proper care, repaired wheels can maintain their like-new appearance for 3 to 5 years. However, new scratches can occur during daily driving.
