How to repair a slightly scratched wheel hub

I、Is it necessary to repair scratched aluminum alloy wheels?
When aluminum alloy wheels are scratched, whether to repair them depends on the severity of the scratches. However, even if it is a slight scratch, it is recommended to repair it in time, because once the varnish on the surface of the wheel hub is scratched off, it will lose the protective layer. Long-term exposure may cause oxidation and corrosion of the wheel hub surface. If the essence of the aluminum alloy is damaged, the wheel hub may be damaged. Needs to be replaced.
The method of repairing scratches on aluminum alloy wheels includes the following steps:
1. Clean the wheel hub to check the degree of scratches.
2. Use paint thinner to wipe away dirt that is difficult to clean.
3. Use water-based sandpaper dipped in water to polish the scratched area until it is smooth.
4. Apply the putty evenly and evenly several times, leaving an interval of 5-10 minutes between each application to allow the putty to dry.
5. Spray paint sparingly every time to avoid paint flow and make the paint color uniform.
6. Spray bright oil to restore the luster of the wheel hub.
Repairing wheels can not only improve the appearance of the vehicle, but also increase driving safety. Because the wheel hub is made of metal, if it is severely worn or damaged, metal shear may occur, causing the tire to rupture, causing particularly great harm to high-speed vehicles, such as a puncture. Therefore, it is very necessary to repair the wheel hub in time.
II、The car wheel hub is scratched, how to repair the wheel hub if it rubs against the curb?
If the wheel hub rubs against the curb and is scratched, it can generally be repaired by self-painting. If the scratch is serious, it needs to be filled. Let dry after putty and then repaint. If the material of the wheel hub is brushed or electroplated, it is not easy to repair the wheel hub of this material, and the repair cost is relatively high. The wheel hub should be dealt with promptly after being scratched, otherwise it is likely to become rusty as time goes by.
When a car is driving on the road, it is inevitable that it will accidentally collide. For example, it is very common for the wheel hub to rub against the curb. After being rubbed, it will cause damage to the wheel hub to some extent, so try not to let the wheel hub rub against the curb when driving.
Tires are the key to ensuring the normal driving performance of a car. The wheel hub occupies an important position in the composition of the tire. It is a cylindrical metal component used to support the tire. It is also an important component located in the center of the wheel that connects the brake drum, wheel disc and axle shaft.
If only the surface is scratched, there is actually no need to repair it. It will only affect the appearance of the car tire surface and have no impact on the safety performance of the tire. If the scratch is severe, or even the primer is exposed, it must be dealt with as soon as possible, otherwise the scratched area will wrinkle and expand, and will rust and corrode over a long period of time.
