Hello Jon,
Your statement: " a DC voltage can be used to prevent corrosion" kept me thinking... it might be worth value to design the electric circuit to help keeping the hideous rust away (I guess this is how Auto's electrical circuit works right??), even if it required to rectify modern hub dynamos AC into DC current.
Would you be so kind as to give general design considerations?

Hey Pablo, I would have to look into the circuit. AC should not be a problem since there is no net flow. I neglected to mention that in some systems a DC voltage can be used to prevent corrosion.. It depends on the direction of the current, it can promote corrode or prevent corrosion.
Salt is no doubt a devil to promote corrosion, so I'm sure in your environment you have seen some things rust in a hurry. You might need to rinse the salt off occasionally and store them dry. Good paint, not using stainless bolted to carbon or low alloy steel, and wax can help immensely.
Tell me the name of the product. I'll get some and send it to you.
