Try this : Drip rail
It will come in a coil, just lay it out straight a few days someplace warm and it will straighten out which makes it easier to install.Use the 5/8" size. Mine runs in one continues strip from the bottom of the windshield to the rear of the quarter window. I may have used a hair drier to make the bend from windshield A pillar to roof. If the wind gets to blowing rain can still make it inside, but it wont be too much.
