We all should know that spurious carbon is always present on the surfaces, and in fact, the carbon peak is typically used to measure charging of samples. So... What was the reference used? Since spurious carbon is variable spatially by samples, and no error data was provided that I recall, how are we saying anything is accurate here? As I recall from reading, there were no replicates and no statistical treatment of the samples. Of course AES should be performed in high vacuum, but I don't recall any treatment on the details of if in the reducing conditions of the beam, if the carbon can change phase/form.
Without XAS, I have severe doubts that these results are indicative of anything real.
This is rather a 'cheap shot' without doing or citing any research to support what you are saying. Regardless of what you may think of the FTC, they have or hire competent technical advisers. If the FTC thought, even for a minute, that the results submitted by Zmax could not be repeated or were not fully supportable, they would have savaged Zmax's case and all the parties involved, including Maurice LePera, with whom they were greatly annoyed.
Understand that the FTC had not yet made their case - they did not have to. They probably thought Zmax would totally roll over following the FTC filing their complaint in court. Suddenly the FTC was confronted with a business-like set of tests that tended to prove Zmax's position. But if the FTC could have disproved even a single claim in the Zmax technical portfolio, they would have done so and the whole Zmax case would have collapsed. This was bloodsport - not some friendly discussion over 'best advertising practices'.
You are simply speculating that this might not have been the best approach. Molakule has repeatedly engaged in this same kind of tactic ("The
only way to really show that any liquid can penetrate..." blah, blah). I guess you just proved that there is even another way to measure things below the surface. So much for Molakule's "only way".

To Molakule's discredit, he spent most of this debate on snarky comments and trashing anyone who thought Zmax's position was not unreasonable, rather than getting even his basic facts correct.

The FTC was faced with a very hard real-world decision. Zmax had shown its cards. The FTC decided to fold. Unless you know of some specific research discrediting the Zmax studies or their methodology, the Zmax technical reports stand as valid. Get over it.
Another reader provided a link to a Youtube
video which pretty clearly shows Zmax soaking into metal. Imagine that! Of course, this was immediately followed by an attack on the studio setting and an attack on the actors. Molakule dismissed it with a snarky comment, while declining to address two key questions: Was it metal? Did Zmax soak in? This debate is not about AES or XPS or anything remotely like that. It's about what is shown in the video and the two simple questions. Only Molakule can't grasp that.
Everyone should watch this
video. Ignore the studio. Ignore the actors. The visual demonstration in this video was what the FTC was facing before a jury of lay persons in North Carolina, had the matter gone to trial. The only addition I would have made was to have a simple horseshoe magnet handy and stick it to the metal sample at the end of the test. With that single addition, a high school physics or chem teacher could have put on this very effective demonstration...
without speaking a single word.

As an aside, there seems to be a kind of agreement that "soaks into metal" has little consumer significance. It is not a 'lubrication' issue. It might genuinely help professional racers who tear down their engines overnight, but that's another matter. So why is there such an obsession to attack this particular Zmax claim?
Or, is it just Molakule's personal obsessive dislike of Zmax? Maybe Molakule did secretly consult for the FTC in this case. It certainly appears that the FTC was guided by a technical person with this same gut-level, non-science emotional dislike of Zmax. It wasn't until the bitter end that they realized they had no case.
You really do not understand anything do you? Man I feel for you.
