Drip rail molding

First of all you need to remove the rear qtr windows and door weather rubber. Then you drill out the rivets. You should be able to hit the rear qtr glass from the inside with a soft rubber mallet or the palm of your hand. Have someone ready to catch it if it pops loose. This way you do not need to cut the inner side of the qtr window rubber.

You may also find a bead of glue was applied between the molding and body. You may need to slide a putty knife between the molding and body to get it to break loose. Caution and take your time, the molding bends easily.

How about the one on the top lip of the door itself?

Now you're talking about the stainless reveal, garnish molding on the outside face of the door, correct? IN MY OPINION, THEY ARE A BEAR TO REMOVE! Again, a putty knife, a bondo spreader spatula, or a strong sharp plastic item where you can get under a spot on the stainless and SLOWLY work the trim molding off the face of the door. If you can get an area to start coming off where it is seated, it will start to pop off. Again, bending is quite easy - take your time.

With the door garnish, only remove if you absolutely have to.
If you bend one and need to replace it, you may find that part unobtainable.
