If you finish it with spar varnish, or another high durabililty finish, it should be perfectly durable. I mean, electric guitars are finished with lacquer (which isnt too durable), and people have been gigging with those for like, 60 years now. I actually think I might undertake this project at some point (should probably focus on trying to actually get gigs first huh....). I've built a number of electric guitars from the ground up, as well as a couple ukuleles. This would be a fun project.
