I recently heard that AMI Instant Roadbed was no longer available. I want to use it to model an asphalt road using a techinque in an old magaine. I read a post on another site about a product similar to instant roadbed used in the heating/cooling industry and available at home improvement stores and heating and cooling dealers. Does anyone have any idea what i am reffering to and what it is called? It is a sticky black material very much like instant roadbed. Any help is appreciated. Thanks.....
