It is much more expensive than my idea of tTiitebondIII mixed with plaster of paris. I watched a video on youtube about using this putty. The Amazon reference for it does not list ounces per tube, so ounce per tube is unknown. I alo got a response from the putty man who said I was dictating instead of participating. Their response to getting a straight edge on guitar plates was a long FLEXABLE SANDING BLOCK they recommended! This may not work out. I get very few responses, and those I do get are things I knew. How did I cancel my enrollment to this site?
