If we are taking Vaseline or petroleum jelly, then there is no beeswax involved.
This kind of thing is easy to verify on the web.  For the facts, one source is
http://www.uselessknowledge.com/explain/vaseline.shtml .  (For fast thorough
searches, I recommend the free version of WebFerret available at

Beeswax and propolis are two things that stick hives together with about equal
adhesion on days cooler than the 80's Fahrenheit. When it gets hotter than that,
they both tend to lose their grip -- in my experience.
