Response from my body work guy (first language is not English!)
yes, Bardahl convert ox rust converter. ( the color of this product is brown liquid and go black or blue up the steel condition, warning if you sanding down you have only 2 hours to zink phosfat pimered. (we learning this way on the shool ) becouse the humidity on the air start again to oxidation.)
some of the rust tetrament work look a like primer.
