I saw a while back about someone using hypalon for a frame on skin yak. The idea intrigued me so I did a little investigating, the only source I've come up with is shipstore.com who estimated I would spend abou $6,000 for the fabric (ouch). Maybe not such a good idea after all. I'd still like to do some kind of plastic skin on frame, anybody have any ideas where to get cost effective (cheap) material and what I should look for?

Thanks
