What should I do if my car windows are not sealed properly?

After the window glass is damaged, it should be replaced with a glass of the same curvature as the original window glass, and the glass guide groove and seal should be checked for damage. As the window often does not return to its original shape after repair, this time, in addition to ensuring that you can easily pull or lift the window glass, also pay attention to the sealing around the window glass after the window is closed.

When changing the roof, you should first apply a layer of conductive sealant around the roof pressed together, to be welded and then coated in the flowing trough and seams all over the folded edge adhesive, which not only helps the body seal but also prevents the body from water accumulation at the flap weld

and early rusting. When assembling the doors, a whole sheet of sealing isolation film should be pasted on the inner panel of the doors below the windows, if there is no formed sealing isolation film, it can be replaced by ordinary plastic paper, and then the sealing isolation film will be pasted and compacted, and finally, the interior panel will be assembled.

When repairing doors with sealing flanges, care should be taken to repair the damaged sealing flanges and accurately restore the shape of the original flanges. After repairing the door, the seal should be checked by placing a piece of cardboard on the seal position, closing the door, and then pulling the paper to determine if the seal is good according to the size of the pull. If the force required to pull the paper is too large that the seal is too tight, which will affect the normal closure of the door, and will also make the seals due to deformation of the large surface faster loss of sealing performance; if the force required to pull the paper is too small, that the seal is poor, often the door will not block the wind and rain phenomenon. In the replacement of the door must pay attention to the new door of the inner and outer plate flap bite at the edge of the coating folding adhesive, and some in the stamping of the small craft holes left with this base tape blocking.

In the repair of car wiring, should be all body holes, and holes in the wiring harness seal installed in place, because these seals not only play a sealing role but also protect the role of the wiring harness. If the seal has been damaged or the harness can turn or move in the seal, the seal should be replaced, and it will be assembled with the body holes, holes, the harness will be stable.

When replacing the whole body, in addition to the above-mentioned items, a layer of sealant should be applied to the lap part of the weld and the weld joint, the thickness of the adhesive layer should be about 1 mm, and the adhesive layer should not have defects such as false adhesion and bubbles; at the folding edge, the special folding adhesive should be applied; the lower surface of the whole floor and the lower surface of the front wheel cover should be coated with 3 mm-4 mm of elastic coating and anti-corrosion coating; the upper surface of the floor and the front The upper surface of the floor and the inner surface of the front panel should be pasted with sound insulation, heat insulation, and vibration damping film, and then laid with heat insulation felt block, and finally with carpet or decorative floor. These measures not only can greatly enhance the sealing of the whole car and slow down the corrosion of the body, but also can greatly improve ride comfort.
