When I spoke to VW last week about my returning wing rust (only repaired 7 months ago), I questioned why weren't the wings replaced instead of "repaired", I was told they don't replace, they just repair. Now from speaking to a friend of mine who works in the body repair business, only surface rust can be repaired, anything more it can't. Wouldn't it be more beneficial for VW if they did the job properly the first time? hopefully they get it right this time, I'm just waiting for the confirmation.
