I just noticed that my passenger door sill plate is loose on one end. Are these glued down normally or do they have another attachment mechanism that I'm not seeing? If they are simply glued is there a particular sealant I should get?

 

Not sure if its held in by clips, but, if its just loose on one end I would suggest using thin good quality two way tape.

 

I am pretty sure they are glued down. Slide a piece of dental floss underneath the edge that is peeling, and work it down the length to seperate... don't pull up on it or it may bend and crease.

Clean off all of the old glue and use something like these to re-glue : Body Trim Adhesive for Cars, Trucks & SUVs

 

Seems pretty easy. I'll give it a try in the next few days and see if it turns out that way. Appreciate the suggestions.
