The only way I can envision treating a stained surface that is prone to drag or lifting is to spray a sealer coat, that would not disturb any surface features.
I can't envision that a surface stained with Vandyke solution would leave a surface coating that would lift.
As far as rafezetter's comments, when I first saw this thread a few minutes after it was posted I was about to make my above comments but decided at that time not to when I realised that the OP has a comercial web site offering very elaborate high end work and partakes in comercial trade shows, as such the request for assistance as worded did not ring true with the claims of the web site.
I know I came across as not particularly forgiving - but I'm glad I'm not the only one that noticed the discrepancy.

I'm sorry you personally don't like my reply Nev - but when people have websites like that, then ask a fundamentally basic question about finishing - it gets my goat, because this is how a customers perception of "what is said, compared to what is delivered" negatively effects those of us in a similar business.
Why didn't the OP ASK the customer what sort of effects the cladding was likely to be subjected to - spillage, children, whatever; what sort of cleaning regimen was going to be applied and WHO was doing it - a commercial cleaners or the staff who probably would have little to no education on what you can and can't use to clean a specific finish used on an oak veneer surface, although to be honest the same could be said for a commercial cleaning company.
I could similarly pull a dozen or fifty pictures from the internet claiming I'm a superlative craftsman - but I ain't, so I don't have one, fact is I don't have one AT ALL, which might account for my less than £6000 earnings last year, or the year before that, or the year before that, and I don't do rubbish work either, you want confirmation ask Eriktheviking, he's let me loose on his house several times.
The OP's question just reeked of "I don't know what I'm doing".
I'm not rich, but I'm honest, and I WOULD HAVE ASKED THOSE QUESTIONS.
When you're a commercial company and have a website like that, but ask the question they did, I'm going to tell it like I see it
Take that how you like.
EDIT: Having got some food inside me and a coffee - I'll bring it down a notch.
If the OP had said "we've been asked to do XYZ, it's a bit of a departure from our normal work - and we would like some advice BEFORE accepting the work" I'd have given that advice, commercial venture or not, but I would have still suggested in future they do thier own research before coming here to get given an answer on a plate, saving them hours and teaching them nothing.
But what it seems like the OP has done is take the commission, FITTED the oak veneering, and is only now wondering what to do to finish it.
It's all pinapple backwards. Add the glossy website and voila - my repsonse came forth.
