rust question

hi I have a friends car and she has had some rust come thru on the bottom body rail. I cut the offending area of rust out and welded a fresh plate of steel andthinking about injecting into the inside of the rail with a rust prevention product. I have acces to a gun that will do the job but was wondering about what to use. I have some tectyl in my shed but was thinking about spraying the inside with Penetrol first then after drying spraying it with the tectyl. I am not convinced I have gotten rid of all the rust and was hoping that by adding either of or both of these products I may be able to stop any unseen rust from growing any further. Any opinions anout my plans would be well recieved as I have necer done this before.
cheers

Rust converter is phosphoric acid. I wouldn't count on it to be a long term rust preventer.

I use odourless fish oil once a year on my 4x4's
it stinks for a week or so then its fine.

ranex works awesome. I cut back the offending area (removing paint etc) and then removing all loose rust and getting a wire wheel onto it. Then spra it with ranex and let it sit for a while, the rust turns black. I then wipe the extra ranex off and paint over the top of it.

Worked on my wagon well.

yep a rust converter of any sort is good but some sort of follow up is even better, fish oil is popular but smelly in summer, Ive gone for coles brand canola oil in a spray can, as it is sticky and not as smelly, other people I know swear by a mixture of (diesel and 2 stroke oil it gets into anything and stays there)

it is just a case of using something that will stop the rust from coming back (hmmm....)
