Some of the sealing parts should be relatively long. The cross-sectional shape of each sealing part is different, and the door opens and closes frequently.

Even if some of them are not aging but damaged, they cannot be repaired, because it is difficult to bond rubber through conventional adhesives. It can only be vulcanized with special glue to re-cross-link the tissue into a whole. This operation is still good for tire repair, but other rubber parts on the car are difficult to be more accurate. The bonding of.

What is the name of the frame under the door of Audi a4l
