I agree with this. The principle this works on is that if the covering is scratched in some manner, the zinc will form zinc oxide and cover the newly exposed iron.

And I see that I am partially incorrect. The chemistry is right, and the situation I saw in my mind is correct, but it is not the one you are talking about. I see the undercarriage of the vehicle covered by road spray - and there being a path for ionic flow in that covering of water. I guess I don't see any difference between that and moist ground. You claim that wouldn't be a path for the ionic flow.

In any case, who cares - I don't enough to try it out, and I live in the rust belt. Two years of driving through salty winter roads and there is minimal rust on my vehicle.
