I’m amazed that people are still ignorant enough to think that aluminium is somehow different…
+1, scratched carbon is unlikley to fail, a scratch on aluminium on the other hand is more likley to become a crack. I’m far happier drilling big holes in the composite parts of my boat than I am drilling even small holes in the aluminium bits.
My other hobbies sailing, failry regulalry the boats capsize in relatively shallow water, often in waves, and the carbon masts get bounced up and down on the seabed and come up scuffed and scratched to buggery. Then go on to lead perfectly normal lives.
It’s actualy recomended to sand down the outer layer of coating down to the fibres then re-coat it every few years (because they spend a lot more time in the sun than a bike, even if they’re stored in their covers)!
