VXOC Astra-J/GTC

As I am someone who is the wrong side of 50, I can remember the days when cars would rust quite badly at a relatively early age.
Vauxhalls these days seem to be fairly well protected from rust, but what I'd like to ask is :

Have you had any trouble with rust on your Astra ?
What are any potential problem areas ?
Has anyone had any rustproofing done on their car ?

I had a recall on mine for rust where the water drainage hole in fuel filler area is traps water and rusts vauxhall drill a small hole fill it with spray grease and seal it again they did it on mine been fine mine was registered in 2012

Pretty much everyone has had that carried out.
