One gallon of neutralizer. The best product to use after you parkerize your parts. Allegheny Arsenal Neutralizer stops the parkerizing process and prevents the white precipitant (oxidized parkerizing) from forming on your parts. It also gives the parts a protective coating. This product is reusable, simply spray onto the parts once they are done or dip the parts into a container of the neutralizer.
