Not sure if it helps but I had a warranty repair on the offside front wing at just 18 months from new. Bubbling of paint had occured around the rear most fixing by bonnet line and where water collects. The wing was stripped in its entirety and removed. Corrosion attended to then local re-paint with two pack colour followed by full re-spray of lacquer. Dread to think what it cost but still fine five years on.
