I'm not an expert on the claim process but seeing as the dealer would be claiming costs back from VWUK I can't see why they wouldn't submit as strong a case for you as possible.
The rust on the wings are a known issue, so I think/hope they will take that one on the chin. The other patches you may have to fight for?
The first dealer I went to told me I'd need to wait almost four months for a paint inspection! The one who did the claim, I managed to catch the fellow by chance. It might be worth ringing in advance and checking if the inspector will be around, so you can maybe try other dealers locally if need be.
Good luck bud.
