My drivers door arm rest is starting to show some wear around the hand hole. It appears as though there are some small plastic protrusions that are spaced regularly around the plastic trim of the hand hole. The protrusions are now sticking up in the vinyl and are visible where my elbow has be resting for the last 20,000 miles. I fear that the my vinyl will wear through. Any body else have this? I will post some pictures this week.
