Does Nissan Replace Original Car Doors with Edge Sealant?

[DeKhloe]

It can only be said that it depends on the integrity of the 4S shop. The presence or absence of edge sealant is not necessarily a criterion for determining whether the part is original. Introduction to Door Edge Sealant: Door edge sealant, also known as door sealing strip, is a product that seals the car door, making it harder to open, and serves functions such as shock absorption, waterproofing, sound insulation, heat insulation, dustproofing, and fixing. It is mainly applied to the door panels, door frames, side windows, front and rear windshields, engine hoods, and trunk lids, providing waterproofing, dustproofing, sound insulation, temperature insulation, shock absorption, and decoration. Targeted Areas: The door sealing system primarily focuses on two areas: one is the sealing of the door opening area, which is mainly achieved by an inner door sealing strip installed around the door opening flange on the side panel or an outer door sealing strip installed around the door. Some car models have both sealing strips, while others use only one. Different models adopt different sealing strategies based on performance requirements or cost objectives.
