I get a link failure on this one.
We used to use the stuff in industry to put the proverbial 10# in a 5#
bag.
I remember seeing a row of electricians (with hammers) beating on a
rigid conduit, particularly at any bends, with two guys pullin' two
soaping, and one feeding. Those cables were never going to come out
of that conduit.
Even though they are not a "tight" fit, I use soap on the bundle of
cables in the underground conduit from the tower to the basement.
