Exhaust dust
So I picked up my Ibis White last week and after driving a while I noticed that the rear of the car had a lot of dust on it. Didn't make anything of it & was just wondering how it could get dirty so fast. This week I took it to the dealer for some perma plate application and when I picked it up it was absolutely clean. When I got back home I again noticed that the rear was dirty and looked dusty. Thats when I realized that the dust was probably coming from the exhaust. Has anyone (with Ibis white) noticed this? It may not be noticeable with other colors. The other ques I have is - will it go away once the exhaust system "burns" in?

It's not so much exhaust so much as road debris and dust. The tail of the car is very flat, which under normal driving conditions causes a dead air pocket from the bumper to the tip of the spoiler on the trunk lid. This dead pocket causes air to eddy there, and particles will drop out of the airstream and deposit on the paint.
