The grease sweats and leaves a lovely oils film for a few inches inside the arch, really does work.
Got to say, I've never worked on a B7 for rust related issues. Mines covered 108k and it's like brand new still. Iam a little OCD with it though. Unless it's had a poor repair at some point in it's life, I wouldn't expect to see any form of corrosion at all. They are well known to be very well corrosion protected.
Well they come with a 12 year corrosion warranty, so could be worth visiting the dealer. Don't worry about paint service intervals, aslong as it's not an outside influence like a stonechip, they should accept the claim, especially if it's an original panel. Worth a shot
To be honest I never visit the dealer, if the engine had problems or I have paint work issues, I usually sort it myself. I work for one of the most reputable skoda dealerships in the uk, and we don't do things that way, so I was hoping that others do the same, clearly not. It's a shame to hear. I would offer my services but my bodyshop has unfortunately stepped back a year.
Wow, I really didn't think these suffered from that much corrosion. Think I would have taken up the £600 contribution though... They would have given you a 5 year warranty on repair, which you could send back 'when' it's returns. Corrosion needs catching early or you have no chance of stopping it unfortunately.
