Just watching the videos Gary, it would be interesting to know where the water ingress had come from. When I stripped down the entire interior before DTEC the interior was just a shell like you have it now and while replacing the ruined carpets with the new ones I noticed that there was water in there. With everything removed it was the perfect time to close the roof and doors and put the hose on it.
What I found was that there was only 1 place that the water was entering the cabin, and that was halfway down the A pillar. If you look at the picture below you can see an area where the shape of the rubber seal changes and when the door is closed you can see it changes how it pushes the rubber against the window. What I found was that water was running along the edge of rubber and window as expected but was managing to ingress at this point and run down to the bottom of the window and down behind the side of the dash and behind where the floor speaker is and gather under the carpets.
To cure this I put a little extra butyl inside the rubber seal to push it harder against the door window and that cured the problem so it might be worth you testing it again at some point in the future to find out if that fix is still working or if the water was getting in somewhere else (Note the roof is pretty new and wasn't leaking when I tested it at any of the joins).
