How Often Should Car Weatherstrips Be Replaced?
1 Answers
The replacement time for weatherstrips depends on their condition. First, check for large cracks or breaks in the weatherstrip. If the weatherstrip is broken, it can be repaired using adhesive. If the weatherstrip is severely damaged or significantly aged, it is best to replace it with a new one. After cleaning the door and window weatherstrips with car detergent, it is recommended to apply a layer of highly permeable protective agent. This not only prevents the weatherstrip from aging but also greatly improves its sealing performance. Additionally, dust and sand can easily accumulate in the gaps of the weatherstrip, leading to rust. Therefore, it is advisable to use a brush to remove dust and sand thoroughly. When replacing the entire body, apply a layer of sealant to the overlapping parts of the welds. The thickness of the sealant layer should be approximately 1mm, and there should be no defects such as poor adhesion or bubbles. The lower surface of the entire floor and the lower surface of the front wheel housing should be coated with a 3mm-4mm elastic coating and anti-corrosion coating. These measures not only significantly enhance the overall sealing of the vehicle and slow down the rusting process but also improve ride comfort. The sealing between the door and the body is a challenging area, requiring strict sealing standards. The sections to be sealed are relatively long, with varying cross-sectional shapes, and the doors are frequently opened and closed. In high-end cars, three or four layers of sealing are often installed, including a quadruple-sealing structure at the front pillars and roof side beams. These multiple seals are usually arranged in the front door gaps and, in addition to their sealing function, also help reduce noise inside the car.
