I scuffed the carbon end can on my ST along its entire length when I lowsided at Rockingham's hairpin.
A week or two ago, I just wet 'n dried all the scratches out and re-lacquered it. You have to look pretty hard now to see any remaining damage. If you look from a foot away you can still just see the very deespest scratches but from any further away they're all but invisible (even though I still need to T-cut the slight sags out of the lacquer coat)
