Todd,
Prior to painting, smear Ospho, brand name for a dilute solution of phosphoric acid, all over everywhere. When dry the surface is primed and ready for the paint of your choice. Worked great for me for years.
Phosphoric acid on ferrius oxide yields ferrius phosphate, an inert salt. Therefore no molecules of oxidation to paint over. Ospho or equivalent is available at box stores and hardware stores.
I have also seen but have no experience with a product called Rust Guy. Ads on RFD TV for farmers and ranchers. They claim it is the end-all for farm equipment.
