Same on both sides so point of contact would be minimal between fasteners and carbon cloth. I know where the deck fasteners will be so could just do a cutout in those areas to be safe!

It is more of an issue with aluminum, as far as I know. But in a saltwater environment, it looks like even stainless will have a hard time?

"Hard points" are often epoxy encapsulated for this reason on graphite composite structures. Kind of a PITA.
Cutouts in the cloth is one way to do it, I suppose. Or potting the joint so there isn't contact?
