I don't remember the source and forget many details, but the test was very compelling. The guy used approximately a dozen different products, clp, wd40, etc. The test involved individual identical pieces of steel all coated with each product and left in wretched environment. 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.
