I soak rusty parts in phosphoric acid I buy by the gallon from Home depot. After I remove a part from it I rinse and scrub it. If it is small enough it then goes in the blasting cabinet for further cleaning. If it is larger I hit it with a knotted wire wheel or 80 grit paper to get to clean metal.

I would not apply any primer or other paint product to a acid dipped part after just a rinse.
