My wife broke her hip so I'm down and out for the moment. I will quiz our chemists to get the latest solutions to corrosion problems. In aerospace, corrosion is a serious concern. Do you want to fly on a corroding airplane? The chelating solution dissolves iron oxide and it is does harm plain iron at all. This is really good stuff. It has no acids that would attack metals.
I see things in this order:
1. Electrolytic rust removal. This hurts nothing and most of the rust is reverse plated away.
2. Use the chelating solution. The electrolytic removal may do all of the work for you and the chelating solution may be unnecessary. I choose the whatever produces the very finest of results.
3. Phosphate the inside to convert the bare iron inside the tank to a phosphate. This is such a good thing that I cannot recommend it higher. This is wonderful for inside tanks or anything else that you wish to paint. I love old cast iron door stops. If I sand blast and phosphate everything. should a paint chip happen, no rust occurs. It's like insurance for all of the work that you do.
4. Paint, now thats another subject. Our non-metallics chemists says epoxy is the only way to go. There again, I cannot comment as I know that many modern surface coatings are top drawer. I will not comment on paint. After phosphating, many many coatings are excellent. I invite paint experts to front and center. Ya, front and center. Ya, I'm old military. I am CIB Viet Nam.
