Well it is a big deal if the product is claiming to be a rust preventative. Not my experience though. It is humid around the great lakes, and also in Japan. I find it very satisfactory. I would not say I think it is the best at rust proofing, but many of the products that claim high levels of performance are not something I want in the shop. As far as FWW tests are concerned, consider the source. It is kinda a variation on Thumper's rule: "if you can't say anything sensible, don't say anything at all". The absolute masters at setting up stupid tests.
