That's fiberglass. For something that big, I would say go get some glass chopmat and fiberglass resin.
Cover your original model in aluminum foil, shinier side out, and spray non-stick cooking spray on it. If you're not concerned about keeping the paper model, glue the foil down, it will help a lot.
Mix the resin and catalyst in small batches, soak a little patch of the chop mat and lay it down on the mold. Keep going until it's all done.
The only thing about fiberglass is that it doesn't do as well on large, flat surfaces. It needs curves to act as supports, or you'll need to add some of your own. Coat hangers can work well for this, or chicken wire if you have it... Hope that helped.
