Ok ... here are the details as requested...
Start with some strips of Gorilla tape (mostly cuz it really sticks well) ... 1"
Front tab of pano roof .... I put some tape across this to add a more solid fit when closing. NOTE the factory TSB added felt just behind.
Now if you open the pano roof to "vent" you will be able to see the the rear tabs that fit into a track on the roof of the car. Second pic shows a larger view of the tabs (there are 3).
If you look from the top of the pano from outside the car, you will see the track these tabs slide in to.
You will see this track goes completely across the car. It is my (latest) presumption, this is the source of the tapping sound when traveling over non flat surfaces. Strategically place about 5 - 4" sections of tape across this track paying particular attention to making sure the tape overlaps the highest part of the the track. You should also be very careful to make sure you place the tape in a fashion to be able to push in to the track on areas where the tabs are located. I used a plastic trim tool to push the tape in to the track. You will see the taped areas in the pic. I did use some electrical tape (which would be preferred) but found it didn't stick as well.
CLEAN THE AREAS FIRST!!
Give it test drive. Make sure you dont create an air leak - if you do, just remove areas of tape. Make sure no sticky part of the tape is exposed to impede opening of the pano. And do NOT place any tape on the left or right side of the pano.
