Use some fine sand paper, like 800grit, and dont take it off, because the clips are most likely rusted and it wont go bakc on, and it will also bend. and new ones are like 100 dollars for the chrome, and like 140 for the mtec black. My passenger side trim ripped of at 130mph down the highway, and smacked the roof, no dammage thank god. just a scrach that was buffed out that same day.
