Roof Corrosion - not just VWs

[AlanM]

As I have an Ocean due in the Spring I have been following the roof corrosion discussion with interest.
So much so that I had a look under the rubber seals of my current van. It is a soon to be 2 years old Fiat Ducatto, HymerCar conversion with a SCA pop-top roof.
You will see exactly the same bubbles as found on T5/6s !!!!!!!!!

Is that a GRP (fibreglass) roof?
If so it will be osmosis rather than corrosion.
