Do Nickles rust faster in salt water or in fresh water?

nickel might passivate and not rust. In general anything that corrodes will corrode faster in the presence of salt water. Totall pure distilled water might not rust much at all due to a lack of ions

Rust being a red or black mix of FeO and Fe2O3, would result in nickel being totally rustproof in any environment. It will corrode, but not oftrn visibly, as nickel salts are often soluble, leaving no trace of where the metal used to be. Iron does not rust in HCl but rather dissolves. Oxygen is as much a part of rust as Iron, and totally pure distilled water is one of the most aggressive acids to metals imaginable. Totally seionized water is "hungry" for ions.

I concur 100%; however, I believe that we need more information about what the guest is calling "rust".

Visible surface rust (iron oxides) require oxygen availability, and as the rusting reaction is electrochemical also need ionic species in the water for electron transfer. Ionic species can be from CO2 dissolved from the air or from HCl or acid salts.

Kas are unsprayed (or more to the point, sporadically sprayed) on the inside facing panels, so rust gradually builds up over the first year and pokes through after about two to three, depending on how damp the inside of the car gets/stays.
