So it was warm and sunny in CO today and I took the plunge and completed this.
Changed out the two B-pillar emblems and one of the 3.5L.
I was going to change out only the ones that were peeling, but I was surprised at how the others, thought still very silver, had lost all of their "chrome" shine. I ended up taking them entirely off and putting the new ones on.
Thanks for the help and encouragement. It looks great and I didn't have to pay the bodyshop a penny!
