Brush on Cinema Secrets Spirit Gum to the back of any area where the Universal Horns 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 Universal Horns onto your skin in the desired area and press into place. For best adhesion, remove the Universal Horns 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.
