How to repair bottom diaphragm connection of Eminent Technology LFT8 planar speakers

These are great ideas. Thank you!  I ordered a conductivity pen with silver ink which looks similar to the items shown above.  However, you will see in the pictures that there is tape covering up the trace printed on the diaphragm, so I think I  need to remove part of tape to expose the silver trace to allow the silver ink to connect to it. 
 
Also, there is no solder connecting the trace to the bottom of the screw posts on the terminal board.  It looks like the screw posts just manually touched the trace with no solder between them. So I will need multiple layers to build up the connection to touch the bottoms of the 6 screw posts. 
I emailed Bruce Thigpen and he said to replace the entire diaphragm at a cost of $250 per speaker. I would like to try repairing the connection first to see if this works.

Some good ideas, but nothing worked for me like a new diaphragm. The fact that it’s a midrange and has a relatively low crossover with a lot of vibration, the repair I made became intermittent again. Good luck and hope it works. Keep the volume as low as possible to reduce the severity of vibration until the glue has cured for a week.

By the way, nice loudspeaker! An overlooked little gem. Only a little more $ than the Maggie 1.7i, and imo quite a bit better.

           The products mentioned above have a much higher viscosity (they're thicker) than conductive ink or paint.    Then: there's the fact that epoxies are manufactured for binding things together (adhesion).

            A small dab, on each contact point would do the trick

            Personally: I'd use pieces of 3M #06383* (or something thinner), to hold things together.

            Not much of an investment, far as an experiment, before springing for a new panel.

Should work fine with the conductive paint as there's no movement there, different story if it was on the middle of the panel where's there lots of movement
I fixed some ML ESL's with the same problem using the conductive paint worked fine never gave any trouble after that.
