What are the drawbacks of door edge guards?

[DeLouis]

The maintenance of door edge guards has three main points: their protective capability is limited, proving relatively weak against significant impacts; being plastic products, they are prone to aging, and removal often leaves marks that affect aesthetics; drivers may develop reliance on them, potentially leading to more severe scratches. The function of door edge guards: Installed on car doors, door edge guards protect the doors from damage. Types of door edge guards: Based on their installation methods, door edge guards can be categorized into three types: embedded, flat, and fixed. Embedded guards are set into grooves pre-formed during vehicle manufacturing. Flat guards involve creating a flat surface on the car with openings at corresponding positions for insertion and adhesion. Fixed guards are secured to the car using nuts and bolts. Care and repair of door edge guards: If the corners of door edge guards peel or detach, use adhesive remover for cleaning, spray and let it sit briefly before wiping off the glue. In winter, heating the double-sided tape with an electric heater before application ensures stronger adhesion.
