Where Does the Water That Seeps Down the Window Go?

[HarleyFitz]

Water that flows into the window will run down the inner layers of the door panel. There are drainage holes at the bottom of the door, which allow the water to drain directly out. Here is some additional information: Consequences of water not draining out: 1. As long as the drainage holes are not blocked and the water can drain out in time, the metal sheet will not rot or rust. 2. If the water cannot drain out, the metal sheet may rust, eventually causing the car paint to blister and the metal sheet to rust through. However, a small amount of water flowing into the door is not a problem, as manufacturers have already considered this. There are drainage holes at the bottom of the door. Additional information: During heavy rain, a small amount of rainwater may flow into the door through the gap between the glass and the outer door seal. This is because the contact surface between the glass and the outer door seal is not rubber but felt. If rubber were used, the resistance when raising or lowering the window would increase, the rubber would wear out more easily, and the sealing might not necessarily be better.
