I would say the RSW stuff is fair game though as it's a standard fairing...
If anyone is up for making their own, I used to use a supplier in Beckenham called Bondaglas Voss Ltd, who are massively helpful in advising you on the best weave and epoxy to use for making specific moulds without those of us unfortunate enough to not have an autoclave... It's surprising how cheap it all is too.
The stuff I used to make up looked amazing, no air bubbles, and looked prepeg, all thanks to their knowledge really. Was just a single layer of straight weave sheet (don't fancy the 3D weave much) with a single sheet of the thinnest glass tissue behind. Weighed very very little.
