The control, ie uncoated piece of steel fared better results that the regular WD40. I remember the best being Clenzoil (I had to grab my can to remember this). However, among the best was.... WD-40 specialist, specifically the "corrosion inhibitor" version. I think it was either the second or third best and I consulted my other can to remember this.
Sadly, my favorite lube ranked very poorly, which was Balistol; however, I'll never give up my Balistol.
I have put both the Clenzoil and Specialist to various 'tests' over the years and can vouch for their quality. But I'd use snot before regular WD-40 unless I was making a stink bomb.
Edit: While not the test mentioned, ProjectFarm (youtoob), who does myriad high quality evaluations, did test various lubes, but I think mostly for lubricity. It was also revealing and I highly recommend it and the channel in general.
