Swaging questions

As swaging is the working of one metal onto and into the gaps of another, and relying on the metal to metal contact for strength-it amazes me that goo would be even considered. Have seen test results and any goo reduces the ultimate strength of the swage.
Stick to the old-timer method of beeswax melted into the swage AFTER swaging. Still the best way to go, all other methods are SCARY!
