I have decades of experience with repairing electronics and as I said in the other forum, replacing that ribbon cable was one of the most difficult tasks I have ever done. Be prepared to spend 4-6 hours, even after you watched a dozen or so YT videos on the process. The cable is very fragile and easily damaged if you make one mistake. The routing of the cable is not well explained in any of the videos I watched so I had to make a few errors on the order to get it right. The ribbon cable comes as a flat piece and it will require you make certain folds for it to fit properly.
As to your specific question, Thunderdrone answered me with a good choice that he has had experience with see the other thread on this topic where I lay out my experience with the ribbon install. I have not used any replacement rubber cement yet and plan to open up the MP later and do that per his suggestion.
As for the GE silicone, or as chemists call RTV for Room Temperature Vulcanization, I would strongly advise not using that in any electronics application where it will cure enclosed space. The reason is the uncured silicone has acetic acid. You can smell it and it smells like vinegar. This was popular back in the 70's but quickly became unadvised due to the acid causing the electronics to corrode and create copper acetate on the connections. Trust me, you don't want that! It's better to use something that is alcohol or solvent based that does not corrode the metal in your circuitry.
You might benefit from reading this thread where I describe what I went through:
"Gimbal Motor Overloaded" = Worthless Mavic
But either way do a search on replacing the ribbon cable on the Mavic Pro Gimbal and spend some time.
Be sure to take pictures of the ribbon routing and folds that you remove before and after removal as that will help you later when you install the new cable. I also use a deluxe tool kit from I Fix it and some head magnifier
goggles to see what I am doing, plus lots of bright light.
Good luck with your repair.
