Scratch on roof - polish?
I have a few nasty scratches on my roof - from a ski rack that came off during acceleration. Don’t ask ...
I was wondering if it’s a good idea to have at it with regular paint polish or if that may make things worse, given that it’s not regular paint what’s on that roof. Any experience in the forum? |

Scratched or exposed carbon fiber tends to readily absorb and collect moisture. I would consider sealing the scratches with clear coat before exposing them to inclement weather.

I know what BMW uses in the i8 is some sort of a carbon fibre / polymer blend. It almost seems like there’s a fairly thick layer of resin on top of the woven bits. |

Ooh nasty, was it a seasucker failure or a user failure? Can't help you with remedial I'm afraid, but you should be able to ask any reputable bodyshop, its just a clear finish on carbon fibre

Another thing - those light scratches on the roof in your pic (not the big scratches) - my car has the same and they don't go away after polishing. They can only be seen in certain light so I left them alone.

Just go and see a detailer. If not gone through clear coat, he'll get it back to how it was before.
If through clear coat, you'll need a bodyshop. Do not attempt anything yourself! |

I used to carry my cross-country skis with the Seasucker rack mounted to the rear decklid window. That always worked like a charm. This time, I was carrying two pairs of Alpine skis. I was worried that their much bigger surface area, mounted at an angle, would create too much lift for the rear glass. So I thought I’d go with a horizontal mount on the roof. Didn’t work out so well... |

Update: The paint guy at the dealer said “ouch” when he saw the scratches. Then he took the car and disappeared for 15 mins. Managed to buff it out 95%. He said he didn’t want to go any further so as to stay within the clearcoat and not get down to the carbon. You don’t see it unless you know what you’re looking for. Thankfully, the roof has that not-quite-glossy, slightly scratchy look to it, anyway. *phew*
