- Summary
- Some customers may complain about rust at the bottom (inner side) of the doors where the seaming welt is located. It is caused by mud/sand adhering to the side sill, which scratches the paint surface when the door is opened/closed. The mud/sand is most likely brought in by the driver and/or passenger when stepping in and out of the vehicle.
