I think its a poylurathane with suspended carbon filliments, it certainly smells like a polyurathane when you spray it, it goes extreamly hard and you can sand it smooth if neccesary, I have used it on a number of my rods after years of abuse with great success, and on replacement wing tubes to bring them up too size, I think Glasgow Angling Centre stock it, they are very efficient.
