Folks,
Just letting you all know for those that keep cars for long periods of time. When I was removing the foam triangles under the front arches I noticed the following on the body:
The plastic arch liners are rubbing through the token amount of paint VW have sprayed on at the factory and leaving it as a bare metal exposed area on the body, and will undoubtably become a problem later on.
I'm currently repairing mine but not sure what to put over it once neutralised and resprayed, seam sealer?

once sealed maybe something like Helicopter tape ?

Aren’t (according to the brochure) body panels galvanised and (this is from my dim and distant past schooldays 45 years ago) a galvanised surface can ‘heal’ itself?

After all the issues with the foam on the MK5 wheel arches you'd have thought VW might have learnt a lesson.

Galvanised surfaces can still corrode unfortunately, and abrasion can remove the zinc coating from the steel.
One side reacted fairly heavily to the rust neutraliser and the other had a much smaller reaction, I resprayed with graphene primer and put a bit of underseal over it for now, but will be going back later and adding better protection. Probably that helicopter tape Jace recommended.
I considered something like dynamat sound deadening but concern that the bituminous material could hold moisture.

I’ve used helicopter tape on my bike where the chain can potential hit the carbon fibre chain stays. Zero damage after 11 years and 100% water and oil resistant.

Dinitrol 447 is very good.

Thanks for the info Willni, will keep an eye out for it. :wink:

Still very low .feel for ya mate, know likes seeing this stuff on our cars . Let me know how u get on as I said when I pull my arches I’ll be checking mine . My mates Gti 2018 at the rear arches have quite a few of zinc inclusions as well so something to keep an eye out for .

Our 2016 car has a fair bit of rust on things like the subframe, drive shafts and suspension arms which I will need to deal with.
My Mk4 Golf had many faults but even at 10+ years old it didn't suffer any rust problems on critical parts.

Only difference is you can get a full new suspension for a mk4 for £400 to sort it if it did.

There is a Volkswizard video that covers potential rust issues on the Mark 7; https://www.youtube.com/watch?v=PxLU0b5fL5k
I did mine last summer on a very hot day, so that it was easy to spray the rust proofer.
