Rust converters not properly and completely flushed will corrode the
parent metal.. I guess I should have mentioned that first but I did

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.

This is the product I used

Treated some rust areas in a truck bed under a bed liner. When I sold the
truck ten years later, the treated areas were still free of corrosion.
