Looking for the paint to touch up the silver exterior trim (door handles, grille trim, etc.). Suggestions as to wear to acquire it would be appreciated. Thanks!

 

Go to any auto paint store. You need paint code XZA. One step paint is easier to use but may not be an exact match to your original paint. If you use a two step paint (base then top coat) the match should be so close you can't tell the difference.
I used the one step paint on the windshield trim and the door handles, painted them myself, two years back and am happy with the results.
There is also a metalic silver with a code of 775 which may be available in a spray can from a Chrysler dealer. Use the search box for Paint Code here on the forum and you can check it out for yourself.

 

Thanks Zip, I'll check it all out!
