Over time, the soft-top has stretched in places, and there is sometimes a gap, created by the pressure differential, between the top of the driver's side screen and the soft-top outer lip.

To counter this, I glued a piece of Velcro to the inner top of the screen and to the inner flap of the soft-top. This attaches the top to the side screen, thereby preventing any gap from forming due to air-pressure differential... And I have to admit, it works really well.
