Wow, that's a good one - how to weatherproof fabric. For a sunshade, I've used a cream colored shade cloth available at Home Depot it is pretty cheap. I folded the edges and put in big brass grommets also from Home Depot - it works really well - then you tie it to your support with twine, wire or rope. It comes out looking like a sail kind of.
I've never weatherproofed big pieces of fabric, normally I think you get a fabric that's already weatherproof.
When I was at Imagineering some years ago and we had to made small fabric props from time to time for outdoors, like the Jungle Cruise or the Indian Village, we would dip the cloth in resin, let it dry to shape, and then paint it afterwards - lasts for years outside, but needs repainting from time to time.
Good luck!
