Rust converters not properly and completely flushed will corrode the
parent metal.. I guess I should have mentioned that first but I did
assume that is a no brainer.

My bad.

over and out.

Not all brands require a flush. Some convert surface rust to a hard dark
grey coating that seems to be an excellent sealer.


Phosphoric Acid (Metal Prep) does just that - used as an "etch" in
auto-body work to give the primer some "tooth" as well as getting rid
of any minor surface "flask\h" rust. Makes Iron Phosphate.
