This is totally one of those that-should-be-obvious-but-I’ve-never-considered-it things from a carbon repair guru. Do note that I linked to the summary of this Luescher Teknik video below because he takes around 18 minutes to get to the guidance. That’s not to say that those 18 minutes aren’t useful, they are, just that it’s easy to get lost in the details before hitting the summary. Which is the good stuff.
