Does any one know MB paint warranty? I have 2003 cl55 and got a few rust spots where paint is lifting. One is on my right side where roof meets the quarter panel. It goes about an inch up and down from where they meet. Like water been getting under there some how. And around my sunroof right where it meets the seal. Does anybody have this problem? As far as i know no paint work was done on theese panels but the car did come with full Lorinser body kit. I cant seem to get the truth on MB paint coverage as i have this on my car for two years now but resently it started to get worst.
