Preliminary Procedure

  1. Lift the roof panel molding in order to access the retainer clip.
  2. Carefully cut the epoxy bond at both edges of the retainer clip using a sharp tool.
  3. Cut far enough into the epoxy in order to help release the retainer clip and not damage the painted surface of the ditch.
  4. Protect the painted surface of the ditch using a clean towel when releasing the retainer from the ditch.
  5. Clean the remaining epoxy using a 50/50 mixture by volume of isopropyl alcohol and clean drinkable water.
  6. Use fine grit sand paper to scuff the bonding surface where the new retainer clip will be installed.
  7. Wipe the surface with the alcohol solution and let the solution evaporate prior to bonding the new clip.
  8. Position and secure the retainer clip with the molding attached.
  9. Press the ditch molding into the ditch to achieve proper positioning.
  10. Apply the epoxy to the underside of the retainer and clip into the final position.
  11. Ambient and body panel temperature should be at least 21°C (70°F) prior to bonding.
