Dear List, Several years ago we did a dinosaur track exhibit. Using a fiberglass mold, we made a footprint using cans of spray foam insulation. We then used spackling compound to give the texture of rock and used dry pigment paint added to the spackle to get the color of the rock. The track is cracking and has been patched several times. I am debating how to fix it. Has anyone made dinosaur tracks? What did you use? Did you have any problems? How did you fix them? This is a hands-on display so sometimes gets lot of not so gentle touching. Thanks for any suggestions.
