I didn't have a lot of time tonight so I only managed to install the rain rails. I formed the first one using the door outline and then tried a different approach (which worked out much better) on the second one.

Line up where you want the rail to start and drill a pilot hole. Attach the rail, and move to the next hole forming the rain rail along the contour of the door as you go. Much easier and cleaner install. Don't forget to remove and caulk behind the rail.
