a very long result, but he is all over the board, he compares penetrants, with lubes. they are not meant to do the same thing!
But many people DO use a particular product for everything, even though that is not their intended purpose. (Many people think "oil" means "lube and protectant.") As such, for lots of people, the results of this sort of thing are indeed useful.
(And some of the ones he tests are indeed both for lubrication and protection.)
Overall, a useful set of tests that hopefully will get people thinking. Or not.
