1. Check whether the sealing strip has any large cracks or breaks. If the sealing strip is broken, it can be repaired using adhesive. Especially with the special adhesive for sealing strips, it is easy to repair large cracked strips. Of course, if the sealing strip is seriously damaged or aged to a large extent, it is best to replace it with a new one to save trouble.

2. After car owners use car detergent to clean the door and window sealing strips, it is best to apply a layer of highly permeable protective agent. This can not only prevent the sealing strips from aging but also greatly improve the sealing performance of the sealing strips. In addition, the gaps between the sealing strips are easily filled with sand and dust, causing rust. For this purpose, sand, dust, etc. should be removed with a brush.

3. When replacing the entire car body, a layer of sealant should be applied to the overlapping part of the weld. The thickness of the glue layer should be about 1mm, and the glue layer should not have defects such as virtual adhesion or bubbles. The entire lower surface of the floor and the lower surface of the front wheel cover should be coated with 3mm-4mm elastic coating and anti-corrosion coating. These measures can not only greatly enhance the sealing of the entire vehicle and slow down the rust rate of the body, but also greatly improve ride comfort.

4. The sealing between the car door and the body is a relatively difficult part. The sealing requirements are relatively strict, the part to be sealed is relatively long, the cross-sectional shapes of each sealing part are different, and the door opens and closes frequently. Luxury cars are often equipped with 3 or 4 seals, and a quadruple seal structure is installed on the front pillars and roof side beams. This kind of multi-channel seal is usually placed in the crack of the front door. In addition to its sealing function, it also has the function of car sound insulation and noise reduction.

5. After the car window glass is damaged, the car owner should check whether the sealing strip is damaged when replacing the glass. Since car windows often do not return to their original shape after repairs, in addition to ensuring that the window glass can be easily pulled or lifted, attention should also be paid to the sealing around the window glass. If the gap between the glass and the glass groove is uneven, and the rubber strip has poor contact with the glass and glass groove, the car owner can easily pull off the sealing strip by hand.

6. When replacing the car roof, the car owner should first apply a layer of conductive sealant to the joints around the roof. After welding is completed, apply hemming glue all over the gutter and seams. This will not only help the car body The sealing can also prevent early rust on the body due to water accumulation in the flange welds.

7. Car sunroof is the basic configuration of most family cars. When the car sunroof is opened, the rubber seal track is exposed to the air, which inevitably accumulates dust and even small gravel. Prolonged use may cause the skylight to deform due to wear and tear and clog the drainage holes. Therefore, it is very important to clean the track regularly and lubricate the track.

Although the car sealing strip is a small part in the car body, it can ensure the stability and thickness of the door opening and closing. It can also protect the car from wind, rain, dust, heat and sound, and play a decorative effect on the edges where the doors and windows meet. When the car body is subject to vibration and distortion, the sealing strip also plays the role of buffering, shock absorption, and protecting the glass. Therefore, car maintenance is no small matter, and no aspect can be ignored.
