Hey I am busy tracking down a flickering light problem.

I noticed three of the breakers in my panel have a light coating of an
oily substance. Do any of you have this? Shouldn't these things be
totally dry?

Aluminum wire? All I can think is that someone got sloppy with antioxidant.
There shouldn't be anything else greasy near a circuit box.

Flickering circuit makes me think of oxidized connection--hot
terminal. Result is outgassing of plastic/insulation collecting on
surface, perhaps?

OP, I'd sure be looking very closely at any signs of overheating,
checking for loose connections, signs of oxidation/burn insulation,
etc., etc.

If I didn't find something easily correctible I'd recommend a pro,
espectially if this is new symptom. Could be early warning sign of
potentially serious trouble.
