I have noticed (when removing these clips) that there is generally a blob of urethane or butyl on the top of the clip, and a small piece of double side tape on the very end of the trim. I think this was meant to help the end of the trim stay in contact with the body during high speeds.
The Butyl was "intended" to keep the water from the tires from passing throught the holes in the body at the clips!
