The outer door trim is the black plastic covered trim piece that sits at the base of the window.  The piece will eventually split it's black, plastic covering and cause oxidation and rust of the underlying metal.  Replacement pieces are relatively inexpensive, but it is not a permanent solution; the new pieces will usually dull and fade within a few months, especially in sunny climates.  To save a little money, I like to "clean-up" the old trim piece by cutting all the plastic plastic off, removing all the rust with some sandpaper, and painting it with a good exterior enamel spray paint.  This gives you a long lasting piece that's a lot cheaper than replacement trim pieces!
