Zinc? I seriously doubt it. I have never heard that before. Phosphoric
acid based metal conditioners are to clean & etch the metal so that the
paint has some tooth to stick on better. If there is any coating, it's
probably a very thin iron oxide coating. A treated steel surface makes
MIG welding easier and better welds too. Phosphoric Acid is primarily a
cleaning solution for metals. It also works on nonferrous metals to
include aluminum & brass as well as steel
I have heard that the other metal cleaners are watered down derivatives.
