Im about to gather my things up from the floor in the garage

The car is on the way home from the paint shop and everything is chaoz, but im happy, beacuse getting the car ready instead of taking it apart is much more satisfying
Was thinking about the small "barrelclips" for the side emblems and hood/trunk letters. I bought new ones along with new emblems and letters.
Are they coated with something?
Will they rust?
What have YOU done with them?
The same questions go for all the NEW clips, for the Outside Trim....
