Correct use of dielectric grease?

[floatsome]

Dielectric grease is non-conductive, so I am not sure how best to use it to protect electrical connections. Putting a thin film on connections might not add significant resistance to the connection when the connectors press together, but still allow the grease to inhibit corrosion. Is that the concept?

Floatsome—

Using a bit more grease is usually a wise idea, since it protects the connectors from corrosion by displacing water and reducing exposure to oxygen. If the contact between the two pieces is such that enough grease is between them to cause a problem—you've got other problems with the connection. The connection should be tight enough that it forces the grease out of the way
