max_gain thank you for your reply. They have used some sort of a gauge to measure the depth. The reading on the gauge was at its lowest on the roof, like less than 110. The reading was highest on the drivers door, about 1000. On the wing it was just over 500. Do you know how I can find out if the paint is still in factory spec? Yes I am referring to the corrosion on the lip of the wheel arch. If its a manufacturing defect then could I not take them to small claims court and get a decision in my favor? Also, how can I find out if the car has had a crash before it came out of the VW plant?

I am not sure how to attach a photo in here. Sorry about that.

Hi everyone, I need some help and advice.. I bought a VW Golf mk5 earlier this year. The car is HPI clear. Just like most mk5's (2005 plate) rust bubbles are starting to form on my front right wing. I took the car to a local VW dealer in loughton. Essex. During the visit they inspected the paint by placing a device on different parts of the car body and got to the conclusion that the wing has been repainted and as a result the warranty is void. Is that correct? Or is the dealer just saying it to wash his hands off. Any advice would be greatly appreciated. Thank you!
