After the window glass is damaged, replace the glass with the same curvature as the original window glass, and check the glass guide groove and the sealing strip for damage. Since the window often fails to return to its original shape after being repaired, in addition to ensuring that the window glass can be easily pulled or lifted, it is also necessary to pay attention to the tightness around the window glass after the window is closed.
When changing the roof, first apply a layer of conductive sealant at the press-fit around the roof. After welding, apply the folded edge glue in the flow tank and the joint. This will not only help the body seal. It also prevents the car from being exposed to early rust due to water accumulation at the flange weld. When assembling the door, a whole piece of sealing isolating film should be attached to the inner panel of the door below the window. If there is no sealed sealing film, it can be replaced by ordinary plastic paper, then the sealing film is pressed and compacted, and finally Interior panel assembly.
When repairing a door with a sealing flange, care should be taken to repair the damaged sealing flange and accurately restore the shape of the original flange. The sealing inspection should be carried out after the door is repaired. The inspection method is: put a piece of cardboard on the sealing position, close the door, and then pull the paper, and judge whether the sealing is good according to the magnitude of the pulling force. If the force required to pull the paper is too large, the seal is too tight, which will affect the normal closing of the door, and will also cause the seal to lose its sealing performance due to the deformation of the oversized surface; if the force required to pull the paper Too small, indicating poor sealing, there is often a phenomenon that the door does not block the wind. When changing the door, be sure to pay the edge glue at the inner and outer plate flanges of the new door, and block some small process holes left during stamping with the base tape.
When repairing the car line, all the holes in the body hole and the hole in the hole should be put in place, because these seals not only serve to seal, but also protect the wire harness. If the seal is damaged or the harness can be rotated or swayed in the seal, replace the seal and secure it with the body hole and hole to secure the harness.
When replacing the entire body, in addition to the above items, a layer of sealant should be applied to the lap joints and welds of the weld. The thickness of the glue layer should be about 1 mm, and the glue layer should not be viscous. Defects such as bubbles; special folded edges should be applied at the hem; the 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; on the upper surface of the floor and front The inner surface of the board should be affixed with soundproofing, heat insulation, vibration damping film, then covered with insulating felt, and finally carpeted or decorated. These measures not only greatly enhance the sealing performance of the vehicle and slow down the rust rate of the vehicle body, but also greatly improve the ride comfort.
