Better Chemical to Stop Rust than Neutralized Phosphoric?


(2000)

About Phosphoric Acid uses mild steel metal. After it dried on metal and then rinse off water. Is that considering neutralized? What are the neutralized steps? How should it properly apply before primer to avoid rust growing under painted surface? My brand said it does not have to rinse before apply primer paint. Any help on this is greatly appreciated.

Is there a better difference choice of chemical to control rusting to a stand still, instead of Phosphoric acid?

This is new steel tubing frame (light coat of rust from moisture in air) being build on MCIís bus chassis (former Greyhound coach). Want to protect it well before totally enclose.

Thank you. Jerry Sr in Florida (USA)

Phosphoric acid is not the finish you want before paint.

You want a phosphate coating, which is phosphoric acid along with other chemicals, that imparts a conversion coating to the metal, improving corrosion protection and adhesion of paint.
