You can order Randolph dope from F&M (stits site) along with their Poly-based system. I'm using their stits fabric on a giant aeromaster right now. Attached it with their recommended adhesive, but I'm using the Brodak flavor of Randolph dope for finishing. Called Chip at F&M and had quite a good conversation with him, asking him about the compatibility of the Stits covering with the Brodak Butyrate dope. He gave me the ok, just told me to remember a couple of things... don't mix products, i.e. if you start with dope, stay with dope, if you start with the Stits product, stay with it. And if you use dope, be sure to thin it so it gets a good mechanical bond to the fabric. So far, i'm pretty happy with the stuff. I started to cover it with silk i bought from Thai Silks, but i don't know if it was the dope or the silk, but I couldn't get it to shrink up properly.
