Sounds like 1 of 1000 phosphoric acid products.
Rule 1 on phosphoric is TIME is your friend. Without full wetting of the rust layer all you got is a polished turd.
Full wetting will dry to an iron phosphate layer you can paint directly over AFTER it drys. Figure minimally 2 times the wetting time for drying.
