I'm working on a later old town now that they glassed from the factory. I don't think they started doing glass on canoes for any other reason that it was cheaper to produce. The boat I'm working on had stapled ribs and the hull wasn't very fair. You can see every plank through the fiberglass. Saying that Old Town started doing it so it must be OK isn't really a great argument. At that point, they weren't making them to last. They were cutting corners like the rest of American production.
