Daily maintenance and usage skills of car sealant strip:

1. Check whether the sealing strip has large cracks or breaks. If the seal is broken, it can be repaired with adhesive. Especially with the special adhesive for sealing strips, large cracks can be easily repaired. Of course, if the sealing strip is seriously damaged, or the aging degree is relatively large, it is better to replace the new sealing strip to save trouble.

2. After the car owner uses the car detergent to clean the door and window sealing strips, it is best to apply a layer of high-permeability protective agent, which can not only prevent the aging of the sealing strips, but also greatly improve the sealing performance of the sealing strips. In addition, the gaps of the sealing strip are easily filled with sand and dust, which can cause rust. For this purpose, dust, etc., should be removed with a brush.

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

4. The sealing between the door and the body is a relatively difficult part. The sealing requirements are relatively strict, the part that should be sealed is relatively long, the cross-sectional shape of each sealing part is different, and the door is frequently opened and closed. On luxury cars, 3 and 4 seals are often installed, and the structure of four seals at the front pillars and the roof side beams is installed. This multi-channel seal is generally arranged in the front door seam. In addition to the sealing function, it also has the function of sound insulation and noise reduction of automobiles.

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

6. When changing the roof, the car owner should first apply a layer of conductive sealant on the edge of the roof, and then apply hemming glue in the flow trough and the joints after welding, which not only helps the car body It can also prevent the early corrosion of the body due to the accumulation of water at the flanging weld.

7. The sunroof is the basic configuration of most family cars. When the sunroof of the car is opened, the rubber sealing strip track is exposed to the air, which inevitably accumulates dust and even runs into small gravel. Prolonged use may cause the sunroof to deform from wear and block the drain holes. Therefore, it is very important to clean the track regularly and apply lubricating oil to the track.

Although the car sealing strip is a small part in the body, it can ensure that the opening and closing of the door is calm and heavy, and it can also protect the car from wind and rain, dust, heat and sound, and has a decorative effect on the edges of the doors and windows. When the body is vibrated and twisted, the sealing strip also plays the role of buffering, shock absorption and protecting the glass. Therefore, car maintenance is no trivial matter, and any link should not be ignored.
