DC in jack corrosion question

I have an application that has a DC jack connected to an internal charging circuit. The charging circuit limits the current and voltage when the charger is not attached, but there is some leakage through the transistor.

The jack looks like a typical DC jack. It is nickel plated brass. Due to the nature of the device, it can be exposed to water and water can sit inside the DC jack for a period of time.

Me question is, what it a recommended thickness for the nickel plating in order to minimize galvanic corrosion between the center pin (+) and the outside (-) of the connector.

From the way I read your posting, you need to be thinking insulator more than conductor. The water is definitely a bad scene.
