Something of a contentious issue.How do you do it?

Do you fit them dry?
With sealant on one side?Both sides?
Oil on one side?
Grease on one side?

What is the collective school of thought?

I'm very interested to hear your responses.
 
General "rule of thumb":

Dry gasket: mount dry and clean
O-ring: light coat of the fluid it is exposed to (oil, brake fluid, gear lube, etc.)
Seals: light coat of the fluid it is exposed to on the seal's rubber lip

On engine work, a light coat of assembly lube may be substituted for oil based on keeping the engine external surface "clean", but the metal and sealing surfaces lubricated. But only if the oil will be changed fairly soon after engine is back in operation to get the contaminated oil out of the engine.

Steve and TQ have you covered...in addition using "all thread" or guide pins to line up mating surfaces also help to keep gasket in place "dry" or dab of clean hi-temp grease also works.
