On that note, it seems to me that water gets in and is trapped by the little plastic end cap on each one of the sills. The metal reinforcement bar is completely surrounded by rubber, of course the easiest fix would be a solid window sill, without the removable end caps.
If Chrysler has not released an updated version of this part, and the new ones have the removable cap, I plan on using some silicone and sealing the caps to the sill, hopefully this will prevent the same thing from happening again.
As far as stain removal goes, a good rubbing compound and some elbow grease should remove 99% percent of it. Of course a coat of wax over the area would be recommended as well after removing the rust stain.
