So for those who come and find this thread later and wonder what is what...
Acetic acid is the active ingredient in Vinegar and it forms Iron Acetate when it comes in contact with steel.
When someone can post a link to a study showing the beneficial effects of Iron Acetate as a protection layer against rust or improved adhesion for paint I'll stop calling BS.

Iron Phosphate (formed when phosphoric acid contacts steel/rust) and Zinc Phosphate on the other hand have been proven to work... even with Epoxy IF properly treated.

I'd avoid Vinegar for those reasons if planning on a quality restore... rattle can and rustoleum guys can disregard this suggestion.




Give me ambiguity
or give me something else
