We just got back from vacation in Montreal and Quebec. Had a wonderful time but the weather was misty rain last week. I have a black car (vw golf tdi) and it was white by the time the trip was over. I brought a bottle of ONR to do quick touch ups but gave up after day 2. What do you guys put on your roads up there?

I know I should have taken a picture for you folks, but there just are so many things to do after vacation there just now way I was going to the store with a car that looked so bad!
