Dust and dirt get stuck to Vaseline, grease and other sticky substances.
Some particulates contain metal that can form a conductive path from the
battery terminal to the case. Test your "battery bucket" for leaks by
putting one of your voltmeter lead on the terminal and the other lead on the
case. Dirty car and truck batteries in damp weather often leak current.

Basically I agree about the low melting point of Vaseline, but I see it as
the canary in the coal mine: your batteries and connections shouldn't be
getting that hot!
Anything over 85 degrees and the cycle life of the battery drops fast.
I switch to grease, when I think I might encounter higher temps (like on
my car battery)

Yes, I hate Vaseline - it has a melting point of around 105 deg F, so
even a moderatly hot day will cause it to drip all over the place -
except onto the terminals it is supposed to protect.

Another YES for silicon. We have used it for years. A very thin coat
will last a long time. I have seen the gooey mess for heated vaseline
more than once.
