Hi all, I have decided to build my own cafe racer seat after watching how easy (ahem...famous last words!) it seems to be in this vid. http://youtu.be/AT6P7qaUPLw (sorry - wont let me embed the video for some reason) I've been able to track down fibreglass and resin fine but I cant find the foam blocks he uses for the mould in the video. Bunnings and Clark Rubber are out. Closest I could find were those block florist use for flower arrangements. Would anyone know where I can get some foam blocks or know of something similar I could use? Thanks heaps!
