I've used similar 'rust converters/encapsulators,' but they always turn any
rust black (they go on clear). They do a good job of sealing, though.
Most metal preps I've seen are a mild phosphoric acid, which creates a very
thin coat of iron phosphate on the surface (chemically, not a whole lot
different than anodizing). We used metal prep on the BN2 and, surprising to me,
it turned the steel parts a golden color.

Bob, I have had great success with a product that used to be called
Corroless, but now that it's sold by Eastwood it's called Rust Encapsulator.
Once the surface is properly cleaned, treated with metal prep solution, and
painted with Corroless/Encapsulator, I have never had much of a problem with
re-rusting. I can't verify that Encapsulator is chemically identical to
Corroless, but it works pretty much as well. It comes in a rattle can or
quart/gallon and can be used as a primer or a topcoat.
