Re: WOW ... stop the rust while you can ...
For what ever it is worth...
My Dealer wants to pull the seal and look at it for rust when I bring the car in for headlight replacement (on order).
No word on if this is a warranty covered issue, but I did show them this site and the great pictures Andrew posted. The service manager was suprised and very interested.
They service a few Crossfires and one of the Techs has a roadster.
