Rust Removal solution... Deox

Ok I'll try here before starting a new thread and get flamed...

I have rust problem on my motorbike frame, not structural, but potentialy likely to become structural if I don't take action.

My problem is to find the right product. Stuff like the one above might be good, I just bought a similar product from halfords, that "transforms" the rust within 3 hours into something stronger (??), but I've been told by a friend in france that "rust never dies, it only sleeps!" and that it needs to be killed! I totally trust his judgment (very experienced and knowledgeable rider), but the translation fails me as I cannot find on the intaweb the stuff he recommends me to use...
Basically, it does not transform the rust into something else, it makes it disappear permanently
Litteraly translated it would be "PHOSPHATING ANTI RUST TREATMENT". It is pretty hard core chemical, but apparently it is extremely efficient, and has to be used with care as it is dangerous for the skin, etc... as you can imagine...

Here is the french product I found, I need the british equivalent, in a shop... I'm sure it's there around the corner but I don't know what to ask for...

Because I don't know the correct translation of this in english, google is not of much help and I don't really want to order in France, ideally if I could find a shop in London, that would be great...

Thanks in advance for your help!

I think most things will be fine as long as they are covered properly afterwards
i used some stuff called Fertan when repainting a 50ft and a 40ft narrowboat. 2 years on and not a single sign of rust on either, although it did get around 5 coats of paint to seal it.
Smaller touch ups were done using simple Hammerite Kurust.
