What worries me about this thread is that if this is a double glazed door
the glazing unit should be sealed so the effect described cannot in fact
occur unless its not really a proper double glazed door.

Brian, the door is wood of dubious quality (many deep cracks) with a
sealed double glazed panel in the top half. The method of fitting is
wooden beading or glazing bar at one side, then the sealed unit and
wooden beading on the other side. The sealed double glazed panel has not
been compromised. The light grey undercoat paint has run, or has been
pulled down by capillary action, between the wooden beading and the
outside surface of the glass.

The lack of a seal seems to be between the sealed DG unit and the wood
beading and as others have indicated rain water will run down the window
and into the glass beading join.
