Well
@Vanterrier this is something that anyone who knows me on here will never normally hear me saying, but in all honesty you don't need to apply any kind of rust inhibitor to any Sevel built van as from 2007, they have all been fitted with fully galvanised bodies.
The Renault built vans which included the Vauxhall & Nissan variants were the first vans of the types to have fully galvanised bodies from the 2004 model year onwards.
Possibly the only parts of your van that you might want to apply inhibitor to would be items like the spring hangers and indeed any other heavy duty metal that has been attached to the main body shell during the production cycle.
Of the product manufacturers that you list in your original post, these days in the classic car circles the company that holds an amazingly high place for quality and eficiancy of product is Bilt Hamber and having used them myself for several years I can personally vouch for their superb range, so take a good long look at their very informative website.
The Dynax S-50 spray is truly amazing, in all of my years of tooling around with cars I have never previously experienced a product that has the ability to penetrate impossible locations. It goes on ultra thin and then evaporates and is brilliant for using in box sections and hidden door bottoms. For all more exposed areas the Dynax UB or UC (the same but one os black and one is clear) is the stuff to use.
They also make a cleaning solvent that is for me the be all and end all product that you dilute with water down to the strength you need it, it is called Surfex HD.
One of the big ++++ of Bilt Hamber is that it is a British company and they are very helpful.
As an ex Land Rover owner, [ersonally I got fed up to my back teeth with Waxoyl as it is so out of date and honestly very questionable with regards to performance................... why oh why do so many people including myself, when using this stuff, did we have to re-apply the entire underside on an annual basis?
