3rd Degree Silicone Modeling Compound is an extremely versatile product for creating realistic wounds and other special effects directly on the skin. Just mix Parts A and B together on a mixing palette and then transfer to the skin to model and sculpt your desired effect. No adhesive required! Use 99% Alcohol to thin the product and help blend edges. You can also shape it using a mold to prep your wounds ahead of time. It can be colored before or after it fully cures, which is approximately 10 minutes.
