Magic Sculp the two-part epoxy putty specifically designed to meet the needs of modellers and sculptors alike. This is the original formulation.
Its grain structure is finer than most other products available and it will not shrink or crack, even when formed in large structures. It can be shaped by hand or with tools, sanded, carved, painted; you can attack it with a grinding tool and the cured material will not break apart or lose its shape.
Magic Sculp will cure at room temperature
