How to neutralize rust

I am interested in any processes or products that can be applied over corroded steel and cast iron to incapsulate/neutralize present corrosion and stop any further corrosion. Thank you.

Locktite has a vacuum impregnation process that seals surfaces with a cross-linked polymer. It's used extensively on steels and cast iron. It seems to me that it should work for your situation.

You may consider a rust converter [on eBay or Amazon] for your problem. There are a couple waterbased products available and each has a unique formulation for specific applications and environmental requirements. rust converter [on eBay or Amazon] s are designed to convert iron oxide (rust) to an inert compound and the degree of penetration depends on the amount of and frequency of application and precleaning efforts prior to application; usually only requiring removal of loose or flaking rust. Usually an applicator can apply direct over the rust converter [on eBay or Amazon] with a topcoat. Both products I have used meet EPA and AQMD VOC regulation and are easy to apply.
