Chip-wise my '12 is fine, I purposely kept it off of the highway until I had the nose wrapped in 3M, and even since it's been on the highway just once.
My Grand Prix has been winter-driven since new and its rock chips are very limited, but I went a step further to protect the fresh paint on the Focus with winter just around the corner.
My only complaint with the '12 Focus' paint is that the bumpers are slightly off-shade, and is especially noticeable with Yellow Blaze. Other than that I have no issues to report.
