  1. Clean surface free of grease, dirt and dust. For best results roughen bond area prior to cleaning.
  2. Wear protective gloves. Cut off required amount. Replace disc on remaining portion. To mix, knead with fingers to a uniform colour.  If mixing is difficult, warm to room temperature.
  3. Apply to surface to be repaired (within 2 minutes of mixing) and mould to shape if required.
  4. For a smooth appearance, remove excess and hand rub with water or a damp cloth before hardening begins.
  5. Trim away any excess before initial hardening. Remove any residues with acetone prior to initial hardening. Hardened excess may be sanded or trimmed away once fully cured.
