Hello,
I've just finished a recanvas of a 1944 18" Guide model, and the build sheet said G.S. Green. I used the Rustoleum Hunter Green, and the color is beautiful. The product is pretty easy to work with too. Used a 6" foam roller in one hand, and "tipped" it off with a brush in the other hand. It might be glossier than the old canoes were, but I find that touch-ups are less obvious with glossier finishes as they don't chalk up as quickly.
