Define what you mean by 'durability'. Adding carbon and epoxy to 1/16" sheet will weigh far more than selecting light 3/32". What do you intend to use the wing for? Whacking it into the garage door? Flying it through the local vegetation? Or do you want the model to last for some time? If the latter then keeping the oil out of the airframe is much more important, along with intelligent flying. If you want to keep the wings pristine then make up some wing bags, corrugated cardboard makes good, cheap bags, wrapped and taped around the panels. Use them to store and transport the wings and your model will last pretty well, Ed's have, and he didn't need glass or carbon, just a good finish.
