I'm (very) new to the group, and doing my best to soak up as much know-how as I can.
Would a sacrificial anode help with this situation? I seem to remember a car-maker using them in the past, but I can't recall which one.
If this works as I (in my non-technical level of comprehension) understand, then the current is carried to the zinc anode, which proceeds to do the rusting (oxidizing) before the iron would. I suppose you would need to make sure that all the rust-able pieces have connectivity. Does someone here have more info on this possibility?
I would much rather clip one or two of these somewhere on the undercarriage and replace them now and then.than confine my (someday) DMC-12 to the New England driving season.
