I am not familiar enough with the chemistry of bluing to comment myself....

As to your question: I do not know, and have not yet looked, though I have dabbled with cold bluing in the past...

My first thought on reading the post was that maybe it fills in the surface like waxing your car...but then I recalled the thread about removing rust and a comment from Mule Deer(?) That removing rust was a mechanical process and another that bluing was a type of rust...

So I opted for a government work comment to play for time...

I think I will do some reading tonight...
