Glass Hull to Deck Joint & Composite Bulwarks

Ahoy Team,
I’m about two years out from beginning an extensive refit to prepare for extended cruising. As I spent the last few weeks touching up some failing paint on the wooden coverboards, trim, etc. I couldn’t help but think about ways to make this more bullet proof long term.
Has anyone glassed over the coverboard to seal the hull to deck joint? How about using composites for the bulwarks and supports?
I’m not convinced this is the way to go, but was curious if anyone has any experience here.
Thanks, as always, for the help!
