I just asked for my free sample. I can't tell you what it is like until I get it in my sticky little hands. It is heat based. Instead of using a hot glue gun, you can cut out the shape you want and use a heat gun. I can think of many uses for that. It would be great for collage artists who want to reposition things before gluing down. You can also heat it up again and reposition if you don't like where it is. It would be good for metals and heavier objects that liquid glue might not hold. Don't know until you try it, right? Here is the link:

Let me know how you like it after you get it.
