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.
