It is a converter not a rust killer.
I think you need to be careful when using converters. If you don't remove as much rust as possible by mechanical means then I have found that you're just making a cured crust on top of weak mush. The idea that these converters soak through "pore deep" I have not seen in my tests / playing about time.
Fertan would / could have been an appropriate solution to the spots of rust shown at the top of this page but again because of the nice clean metal around the spots the rust converter isn't ideal - I've noticed that rust converters really don't mix well with solid clean steel. After using a converter on an area such as that shown above you need to go over the area with a wire brush / sander to remove the converter from the clean metal. (All in all a sealing product is less hassle)
I do like the epoxy spray that is meant to go on top of Fertan => Ferpox. In my experience it has turned out to be quite a good all round single component protective layer. It isn't in the same league as the tough two pack epoxy coatings I'm now playing with but it has helped keep rust at bay on my Mercedes suspension components for the last 5+ years.
EDIT:
Fertan does seem to work though.
It reminds me a little bit of Jenolite that used to be the "thing" back in the 1990s 'cos the MOD used it once apparently...
