Two-part epoxy putty specifically designed to meet the needs of modelers, crafters and sculptors. We use Magic Sculpt primarily when working with replicas, but also in the restoration of original fossils. It has a fairly lengthy working time, smooths out with water, and takes texturing well. No shrinking or cracking. It can be shaped by hand or with modeling tools, sanded, carved, and painted. You can attack it with a grinding tool and the cured material will not break apart or lose its shape.
