  6. Apply black primer to the same area as the clear primer in the step above.
  7. Allow the primer to dry.

       • Allow the vehicle to remain at room temperature 22°C (72°F) at 30% relative humidity) for a minimum of 6 hours.
       • Partially lower a door window in order to prevent pressure build ups when closing the doors prior to the urethane adhesive cure.

       • Do NOT use compressed air to dry the urethane adhesive.
       • Do not direct a hard stream of high pressure water at the fresh urethane adhesive.
