What are the drawbacks of car door sill guards?

[DiGideon]

Aftermarket-installed door sill guards are prone to friction with the car door. Moreover, since the sill guards are attached with strong adhesive, they may start to peel off after some time. Here are some related points: 1. Paint scratches: If the vehicle is an SUV and there are children or elderly people in the family, they often step on the car sill when getting in and out of the car, which can cause scratches on the car's paint over time. Installing sill guards can effectively prevent this issue. 2. Peeling off: If the sill guards frequently peel off, it is likely due to negligence during installation. Before installing the sill guards, the sill area must be thoroughly cleaned, and the paint surface must be kept dry and clean. After applying the adhesive, pressure should be applied to ensure full contact with the adhesive surface. A hair dryer can also be used to heat the adhesive to ensure complete bonding.
