Pretty sure that's dielectric grease, too. I've used a small amount of Vaseline, and it works fine. It's also an insulator, but hasn't seemed to cause any connection problems...

It truly works and is recommended in DXE procedures. Look at their website for the details (a pdf file). It is costly and will last years and you can share it with your friends and club members. Just fill up all of the space inside the connector. Then clean all of it off the OUTSIDE of the tightened connection. Then wrap the finished connection with this Scotch Electrical Splicing 130C tape https://a.co/d/enkLUf1 and Scotch Super 33+ electrical tape on the outside. Sealant: https://a.co/d/bVYmN0c Also for Type N connectors, too.
