Will the window leak if the outer window trim ages?

[EvangelineAnn]

Aging outer window trim will not cause window leaks. As long as the window sealant remains intact, there will be no leakage issues. Here is additional information: Sealant strips: In fact, car windows do not rely on the outer window trim for waterproofing, but rather on the sealant inside the glass. The outer window trim mainly serves decorative purposes and helps delay the aging of the window sealant, so there is no need to worry excessively. Avoid prolonged sun exposure: If you are still concerned, you can check for leaks during car washes. If any leaks are found, the sealant should be repaired promptly. Additionally, try to avoid frequent exposure to direct sunlight, as UV rays can accelerate the aging of the sealant.
