What are the disadvantages of wheel hub brush repair?

Wheel hub brushing has the disadvantages of being prone to oxidation and developing black spots. After repair, brushed wheel hubs generally affect the aesthetic appearance. Here is some relevant information about wheel hubs: 1. Introduction: The wheel hub is the rotating part of the tire's inner contour connected to the wheel steel through columns, which is the metal component mounted on the axle that supports the tire. It is also called the rim, steel ring, or wheel. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Types of wheel hubs: Wheel hubs are also called rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of wheel hubs will also adopt different methods, which can be roughly divided into two types: painting and electroplating. The wheel hubs of ordinary vehicle models consider less about appearance, with good heat dissipation being a basic requirement. The process generally uses painting treatment, that is, spraying first and then electric baking, which is cost-effective, with bright colors and long-lasting durability. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged.
Wheel rim polishing repair might sound cost-effective, but it actually comes with significant issues. The polishing process removes a portion of the metal surface, weakening the rim's structural integrity. Having repaired several cars, I've often seen that polished rims are prone to deformation or cracking, especially when driving fast on rough roads—posing serious safety risks. Over time, the risk of corrosion also increases significantly, particularly in rainy regions where rust spreads faster. Repair shops frequently fail to restore the rim to its original factory condition, resulting in uneven surfaces and a pitted appearance that affects aesthetics. Additionally, if the repair technique is subpar, the wheel's balance can be compromised, leading to vibrations or noise while driving. Considering all factors, in the long run, replacing the rim entirely is a safer and more durable solution. Trying to save a little money may end up costing more and involves unnecessary safety risks.
As a car owner, I'm quite particular about the aesthetic details. After the wheel rim's brushed finish is repaired, the surface just doesn't feel right—it's hard to achieve perfect color and texture consistency. The original brushed effect had an even gloss when the car was new, but post-repair, it appears patchy with slight color variations, which really affects my car's overall appearance. This becomes especially noticeable under sunlight, and every car wash seems to highlight this flaw. During the repair process, minor scratches or uneven treatment might occur, making the rims more prone to dust accumulation or oxidation, requiring more frequent maintenance. Over time, the repaired layer can also peel or discolor, making the wheels look aged—far from the original's durability and appeal. Although it's cheaper, the significant drop in aesthetics makes it hardly worth it. I often worry while driving that the condition might suddenly worsen, impacting the overall experience.
