Rust converters
What sort of products have you used and can recommend?
Mainly for pitted areas that are too good to replace.
Thank you

Re: Rust converters
I succesfully used a product called "Tiger Rost KO" , which is basically phosphoric acid. It requires multiple application, with wire brushing inbetween to work it into the rust and remove rust that has already been "disolved". It is available at our local Austrian DIY shop. Any similar prodct will work in the same way. My choice any time.
Another option for vertical areas is DEOX, whic his a gel and doesn't run of - I think it is too phosphoric acid based. Available in the UK via bilt hamber

Both are rust removers, I have no positive experience with rust converters - which say to convert rust into a stable iron-tannin - they only seem to work on flash rust.

Hammerite Kurust seems to work ok for me on small areas of surface rust:-

Re: Rust converters
I cannot emphasise enough to stay clear of so-called rust converters or rust encapsulators - from my experience they only work on flash rust or the like.
If you have heavy corrosion they won't work into the rust deep enough to provide long term remedy.
You have two options: rust remover (acid based) which is a long process of applying, letting it do its rust etching process, wire brushing of the layer and re-application, ... etc.
apply suint based oils that penetrate the iron-oxide particles and "encapsulate" them from further oxygen ingress and such stop corrosion. Fluid film is my choice in that category of corrosion preventatives.
First choice is always media blasting where possible.
If you have removable parts soak them in phosphoric or citric acid.

Re: Rust converters
I've used both Vactan and Dinitrol RC900 before and had good results. Dinitrol is a tad expensive though and I would say no better than Vactan.
They both worked fine for me with no rust coming back in the time I owned the car (over 3 years) so I would use them again, although according to the internet some people don't have any luck using them so it's a case of suck it and see really.

Re: Rust converters
My problem areas are inside the quarter panels where the soundproofing was adhered, it's held the damp obviously, front bulkhead too.
I don't trust anyone to blast the quarters without warping them.
