I took a quick look at the ITS report pdf. It says the test was done by immersing the panel in a saline solution. My friend was able to get some painted panels from an engineer who worked at Ford and was interested in the test. He then hooked up one of the devices (he borrowed it from someone who owned one) and sprayed the panels with a periodic spray of saline solution. I think the full test ran for 6 months. The idea behind the spray was that it would more closely approximate normal usage on a car, and not marine usage, where things like sacrificial anodes for corrosion protection are common. The painted panels started corroding within a couple of months and were pretty damaged by the end of the test. A lot of the corrosion started at the edges where the metal was bare, but there was corrosion that started in the middle of the panels as well. I figured that the edge corrosion would be similar to what would happen to a surface with a scratch in the paint. He did have some panels in another enclosure that were not connected to one of the devices. There wasn't much, if any difference between the sets of panels. They all rusted. The test was done in the late '80s, so I'd expect that coatings technology has greatly improved since then, plus I know that at least some (all?) of the car makers now use galvanized steel for body parts. There's possibly less need for one of these devices now than there was. I'm not telling anyone what to buy or not buy, but I know that for myself I wouldn't spend the money on these gadgets. I'd rather put that money into washing my car to try to clean the salt off. I think my friend wound up having more fun building the test rigs than anything else. Running the tests themselves was about as fun as watching grass grow. :-) BTW, I'm not disputing the electrochemistry that's the basis of these devices. I'm just not convinced that it applies to these devices in the real world on cars being driven on roads, particularly in areas where they're exposed to salt.
