Please help a little girl living in the south of England, bought a 2004 modal 6 months ago. Had some bad weather,washed it down and tucked it up in a heated garage when it got wet, and yet the alley has excessively corroded. polished it off with a lot of elbow grease and sent it off to be prettied up for px for this years modal. The garage left it outside for a while and within a couple of days b4 they got to work on it the rain created a fur coat on the alley casings.Is this a plating problem therefore warranty covered or is there a way of protecting it i am not aware of.
