The sealing strip is a rubber product, which is easy to oxidize and harden after being used for a long time, resulting in a less comfortable driving experience. For example, when you just buy a new car at high speed, you will feel that the sound insulation effect of the vehicle is good, but after driving for 2 years, at the same speed, you obviously feel that the sound insulation of the vehicle is not as good as before, which is caused by the aging of the sealant.
Like the general car wash, the sealant will not be particularly carefully treated, so if you want to maintain it more comprehensively, you can go to the car owner platform and find a reliable car wash shop and car beauty institution for comprehensive maintenance. Of course, they have recently had activities and discounts for maintenance, so you don't have to worry too much about the cost.
As for the question of whether maintenance is required, there is indeed a way to maintain the sealant, which can improve the service life.
1.Pay attention to check the sealing strip for large cracks and cracks on a daily basis. If cracks are found, they can be repaired with binders.
It is best to use a special adhesive for sealing strips, which can easily repair large cracks.
2.Avoid high temperatures and cold. In the hot summer, it is best to park the car in a cool place, and try not to expose it to the sun in the high temperature; When it snows in winter, it is best for qualified car owners to cover the car coat, which can effectively prevent the impact of low temperature on the rubber strip, and at the same time prevent the snow from melting and making the rubber strip freeze and age.
3.The gaps in the sealing strip are easily filled with sand and dust, which can lead to rust. When washing the car, do not directly aim the water gun at the sealing strip, the correct way is to use a brush to clean the gaps of the adhesive strip.
After cleaning, remember to apply a highly penetrating protectant to the strip.
4.When the glass of a car window is damaged and the glass needs to be replaced, it is important to check the sealing strip for problems. Because repaired windows often don't return to their original appearance, keep an eye out for seals adjacent to the window glass.
If the gap between the glass and the glass notch is uneven, and the rubber strip is not in good contact with the glass and the glass groove, the sealing strip can be pulled off with a single pull.
5.Cars with sunroofsWhen the sunroof is opened, the rubber seal will be exposed to the air, and dust and some small gravel will inevitably accumulate in the sunroof track, so the sunroof should also be cleaned regularly and lubricated.

The aging of automobile sealing strips requires timely replacement of sealing strips.
Seals are rubber products used to seal around the door to improve airtightness and prevent wind and rain from invading the cabin. Once the door seal is damaged due to aging, it will cause rain leakage in the cabin, increase the driving noise of the car, and the rain leakage will easily make the body rust. For automobiles, the sealing strip is an important part that must be regularly maintained and inspected.
The first is to check whether the sealing strip has any major cracks and whether there are breaks. If the sealing strip is broken or has a large crack, it can be repaired with adhesive. In particular, it is easy to repair large cracks by using a special adhesive for sealing strips.
Of course, if the seal is badly damaged, or if it is more aged, it is best to replace it with a new one. Since replacing it yourself may cause a poor seal, it is still necessary to ask a professional to replace it.

For car owners with economic conditions, it is recommended to use a special reflective car coat for automobiles, which can effectively avoid cracking of the sealing strip due to heat. In addition, choosing a maintenance paste for the sealing strip can restore the elasticity of the sealing strip.
In the cold winter, the temperature is generally low, and after washing the car, the sunroof glass and sealing strip are likely to be frozen, so it is recommended that the owner do not force it to open it to avoid damaging the sealing strip. In addition, once the sealing strip is aging and cracking during the driving process, it will not only affect the sound insulation effect in the car, but also cause water leakage and water seepage in serious cases. Therefore, it is necessary for the owner to maintain it at ordinary times.
Precautions for replacing seals.
1. Before replacing the sealing strip, you must choose the appropriate style according to the sealing strip used in your own car model, and the models matched by different sealing strips are also very different.
2. After selecting the sealing strip, the original sealing strip should be removed before installation, and the area covered by the sealing strip should be wiped, and then a layer of protective agent should be applied before installation, which can prevent the sealing strip from aging and improve the sealing function of the sealing strip.
3. When replacing the door seal, there are usually one or two water outlets on the door, and do not block these drainage holes to avoid water accumulation in the car.

<> "Daily Maintenance of Automobile Sealing Strips.
Inspect the door and window seals for large cracks or breaks. If a broken seal is found, it can be repaired with a special adhesive for the seal. With this special adhesive, large cracks can be easily repaired.
Of course, if the seal is badly damaged or has a high degree of aging, it is better to replace it with a new one, which is more convenient.
After using car detergent to clean the door and window sealant strips, it is best to apply a layer of highly permeable protective agent. This prevents the weatherstrip from aging and greatly improves the sealing performance of the seal. In addition, the gaps in the finger strips of the sealing pin can easily be filled with sand and dust, which can lead to rust.
Therefore, sand and dust should be removed with a brush.
When replacing the entire car body, a layer of sealant should be applied to the lap of the weld. The thickness of the adhesive layer should be about 1mm, and there should be no defects such as false stickiness and bubbles. The lower surface of the floor and the lower surface of the front wheel cover should be coated with an elastic coating of 3mm to 4mm and an anti-corrosion coating.
These measures can not only greatly enhance the sealing performance of the whole vehicle and slow down the corrosion rate of the body, but also significantly improve the ride comfort.
The sealing of the door and the body is a more difficult part, the demand for sealing performance is higher, the part that needs to be sealed is longer, and the cross-sectional shape of each sealing part is different, and the door is also frequently opened and closed. Luxury sedans are usually equipped with 3 or 4 seals, as well as quadruple seals on the front strut and roof side beams. These multi-pass seals are generally arranged in the front door crack, and in addition to the sealing function, they also have the effect of sound insulation and lead noise reduction.
After the window glass is damaged, the owner should check whether the sealing strip is damaged when replacing the glass. Since the windows often do not return to their original shape after repair, it is necessary to pay attention to the tightness around the window glass in addition to ensuring that the window glass can be easily pulled or lifted. If the gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass and the glass groove, the owner can easily pull off the sealing strip by hand.
When changing the roof, the owner should first apply a layer of conductive sealant at the pressing place around the roof, and then apply the hemming glue in the flow tank and the joints after welding, which not only helps to seal the body, but also prevents the body from early rust due to water accumulation at the flanging weld.
A car sunroof is the basic configuration of most family cars. When the sunroof is opened, the rubber sealing track is exposed to the air, which inevitably accumulates dust and even runs into small gravel. Prolonged use may cause the sunroof to deform due to wear and tear and clog the drain holes.
Therefore, it is important to clean the tracks regularly and apply lubricating oil to the tracks.
Although the car sealing strip is a small part in the body, it can ensure that the door is stable and heavy, and can also make the car shelter from weather, dust, heat and sound, and play a decorative effect on the edge of the door and window handover. When the body is vibrated and twisted, the sealing strip also plays the role of cushioning, shock absorption and protective glass. Therefore, car maintenance is no trivial matter, and no link can be ignored.

3. Do not close the door too much, and do not use too much force when closing the door, otherwise it will have an impact on the sealing of the door, and it is easy to cause subtle deformation of the door after a long time.
4. Pay attention to the sealing strip that protects the doorWhen opening and closing the door, be careful not to touch the sealing strip, otherwise it is easy to damage the adhesive strip. Especially in winter, once the door is frozen, don't force the mold section to open the door, and let it thaw naturally.
5. When opening the door, some Madahar likes to open the door very much, and the force is more violent, in the long run, the folding of the door will be squeezed and deformed, and the door will not be so tight.
Daily detail maintenance:
1. The hinges are often lubricated, and the door opens and closes freely Because the door is often opened and closed, some passengers or drivers will vigorously open and close the door or open the door very widely, and the door hinge will be worn and deformed over time, and the door is not closed tightly. Keep the door hinges lubricated frequently to reduce the degree of wear. When opening and closing the doors, close or open the window panes completely.
When the window glass is ajar, the vibration impact of the door is large, and the windows and doors are easily damaged; In addition, when closing the door, gently open the door between 20° and 30°, and then close it a little harder, so that the door hinge can be durable and the door can be opened and closed freely.
2. Apply protective agent, anti-aging sealing strip The rubber sealing strip around the door plays a role in improving air tightness, if aging and damage occurs, it will cause water leakage in the compartment, increase the wind noise and other troubles. During maintenance, because it is easy to block sand and dust between the gaps of the sealing strip, the sand and dust should be cleaned frequently with a brush, and then coated with a layer of highly permeable protective agent to prevent the aging of the sealing strip. Seals need to be inspected, maintained, and replaced regularly, and it's best to remove them when repairing them, applying protectants, or washing cars.
The function of the door seal: The sealing strip installed on the door of the car is generally made of rubber. It is found in both door and window glass, and its function is mainly to isolate the interior and exterior of the car.
For example, rainwater, river water, sand and dust and other substances, as well as heat insulation, thermal insulation and sealing of the car. When the car glass is subjected to large vibration, the sealing strip can also play the role of buffering, decompression, and protecting the window.
