I don't have access to the article, where did paste wax rate and what was the best?
Some time ago, long time ago, for work we did tests on automotive coatings, metal treatment before and corrosion resistance.
I guess there will be a lot of subjectivity as to how this should be tested, however I doubt it that FWW would have access to the test equimpment needed for measuring permeability of moisture through barrier materials as well as the effects of all the factors that start the chemical corrosion process.
All I know is my shop was together one year this May, in storage for 18 months before that and I have no corrosion whatsover after rubbing Johnsons Paste wax on liberally, and leaving it 2 1/2 years ago, in central NC.
