Brush on Cinema Secrets Spirit Gum to the back of any area where the Deadly Screw is touching the skin. Cinema Secrets Spirit Gum may also be applied directly to the skin, especially on larger pieces. Hold the appliance against the skin to determine proper placement. Although most of the appliances can be worn in several places, it is best to check for proper alignment of some pieces. Edges may be trimmed for a better fit. Position the Deadly Screw onto your skin in the desired area and press into place. For best adhesion, remove the Deadly Screw and use the piece itself or your index finger to tack the Spirit Gum with a rapid up and down motion. This will cause the Spirit Gum to become extremely tacky. Then Firmly press the piece back into place. Using a cotton swab or brush, apply Cinema Secrets FX Blood Gel to any area you desire to have a thick gooey look. For a more realistic look you can add Cinema Secrets FX Blood, to give you a freshly bleeding look.
