I had heard that the Coolflex had a tendency to flex and distort somewhat as is heated up. I have no first hand experience with the product myself. For most applications the amount of flex would probably be tolerable. However in the application that Renaissance man had in mind, this flex might be too much. Possibly Raceral or someone else could report on the amount of temporary distortion (if any) they have experienced with Coolflex.
