Okaayyyy, so what exactly do these "rust converter" products do?

Given how many $$ and hours the metal and paint industries put into
coping  with rust, they sound like snake oil to me.  I have an aerosol
can of one brand that I've dicked around with a bit without learning
much. Yes, the red stuff turns black.   And?

So what's the chemistry?  Fe+++ -> Fe++?  What happens at the surface
the base metal underneath?  To the water of hydration in the red rust?
What what?
