Modern cars have a rubber strip to prevent water coming into the door panel. I have nothing in the doors of my 26. I am wondering if there should be. Without in a rainstorm, a lot of water could run inside the door.
That’s an interesting idea. My concern is the gap between the outer part of the door and the glass. I have added a sketch. The lip of metal at the top of the door is probably only about 1/4" so not much to grab onto but it is worth a try. Thanks for the idea. I will give it a try.
