Help: Bed temp sensor disconnected

I was changing the bearings on the Y axis and I accidentally ripped one of temp sensor wires out of heat bet. I was able to undo some of the thermal tape, get into it, and reconnect it. It works, however it looks like I need to retape the tape flap that I had to undo that is over the power and sensor connections on the bed. What kind of tape or adhesive can I use to seal the tape flap back over the bed connections?

RTV. Really lots of things would probably work, but RTV is what I would use. Auto parts stores sell it.
