W210 holes in front wings from rust - Corrosion Guarantee?

[Rustbucket]

For genuine inside-out rust, Mercedes 30 year Mobilo-life scheme will cover it, as long as you have kept to all the T&C's.

I've yet to see a genuine case of inside-out rust due to the inside of the panels being galvanised.
Normally the rust starts as "raw edge corrosion" and spreads from there.

Mercedes state that when they say inside to outside, Inside means, and I quote "inside the actual Metal"

They say it has nothing to do with galvanising or interior / exterior coatings on the surface. The rust must start from within the metal itself!

Therefore mobilo life will never cover any corrosion, even if you meet all the T & Cs.
