What should I do if the car hub is scratched?
1. See if the hub is broken.
First of all, whether the hub can be repaired needs to be ruled out. There is no way to repair a wheel hub with cracks, deformation or complete fracture on its surface. In this case, for safety reasons, only a new one can be replaced. If your hub is not broken and deformed, it can be repaired. Next, the maintenance master will tell you the maintenance method of the wheel hub, so that you can go to the 4S shop less and waste money.
Step 2 clean the wheel hub
Be sure to clean the hub before repairing, so that the subsequent painting effect will be better. Remember to wipe the hub with a towel after cleaning, and pay attention to wipe off the oil stains on the surface of the hub with degreased waxing paper after cleaning. Leaving oil stains will greatly reduce the effect of painting.
Also, when cleaning the wheel hub, you can also clean the iron chips and stones on the wheel by the way to avoid secondary scratches when using it in the future. But also know the depth of scratches on the hub and whether there are any big cracks. This step cannot be omitted.
3. Fill the scratches on the wheel hub
After cleaning the wheel hub, we gently polish the damaged area with fine sandpaper until it becomes smooth and flat, so that the scratches look much shallower. Then put the putty we prepared on it. Note that when daubing putty, it must be daubed several times every ten minutes, so as to fill the dent well and ensure the putty to be dry normally.
4, painting and oiling maintenance
Finally, the more serious damage is painting the wheel hub. Before painting, you can cover the parts that you don't want to paint (such as tires) with paper to prevent the hub spray from getting on the tires. When painting, spray a few times more, and spray a little less at a time, so that there will be no painting, and the sprayed paint will be more uniform. After spraying paint and varnish, the wheel hub of the car will become as bright as new. Or polish the whole hub with car wax.
The following are the specific steps of patching:
1. Check the scar. If it doesn't damage the inside of the hub, it can be repaired simply. Wipe around the scar with paint thinner to remove dirt.
It is difficult to remove the dirt from the deepest scratch. At this time, you can clean it thoroughly with a toothpick.
3. In order to prevent irrelevant parts from being smeared by mistake, it's best to stick adhesive tape around the scar carefully.
4. Tidy up the nib and apply decorative paint. The paint will shrink slightly after drying, so it's better to apply it a little.
After painting, it will take about a week to dry completely. After drying, soak the waterproof paper in soapy water to make the surface smooth.
6. Wipe with water-resistant paper, then polish with mixed liquid, and then wax. For deep scars, it is important to observe whether the metal surface is exposed. If the metal surface is invisible, it will not rust, and you can concentrate on painting decorative paint.
How to maintain the car hub?
1, often scrub the hub.
The exposed hub is the easiest to get dirty, and it is also easy to get dirty when driving through a puddle, so it is necessary to scrub the hub frequently to ensure the cleanliness of the hub.
2. Use special hub cleaner.
To make the hub more beautiful, it is good to use hub cleaner regularly, which can add a layer of protection to the hub surface.
3、? When scrubbing the wheel hub in winter, if the temperature is below 0 degrees, be careful that the brake disc freezes, so it is best to scrub or clean the wheel hub in the sun.
4、? When scrubbing the wheel hub, it is best to use a soft cloth, not too hard. After all, the surface of the wheel hub is also painted to avoid damaging the paint surface.
5、? Many cars' wheels are afraid of injury, so when you pull over, you should pay special attention to the fact that the wheels don't touch the curb, and you should know what you are doing.
6、? When scrubbing the hub, also consider the inside of the hub. It's difficult for a general car wash shop to wash the car so deeply. It's up to you to be more thorough.
