Keeping water out... grrr

[mateo1279]

Any ideas on how to seal the gap between the window glass and the outside edge of the door? (...where your arm would rest when riding with the window down)
I am sick of water flowing into the door and out of the rusty door bottom. Gotta fix this before fixing the rust or doing anything nice to the interior at all....

The products and kits don't look like they include a seal for this spot.... just the vertical channels.
