This is the part I was referring to. Zinc phosphate is parkerizing (patented trade name). Sometimes when I parkerise you also get some white or streaky looking finish. It has to be rinsed and oiled or as I and may do rinsed and painted over which is a very good finish. The paint I use is molyresin which must be baked/cured for an hour at 300 degrees. Many military firearmes have just the phosphate but are well oiled over the years. I have a few and like the look.

Very resistant to corrosion but IMHO way overkill for the automotive aplication. Again just trying to add info.
