Remove damaged strip seal without any damage to the parent material, and remove the remaining compound.
SUBTASK 72-32-86-330-051 Remove the Damaged Strip Seal from the Rear Fairing Assembly
Refer to Figure.
Refer to the SPM TASK 70-11-26-300-503.
Cold liquid degrease the mating surfaces.
Refer to the SPM TASK 70-36-02-360-501.
Hand clean the mating surfaces.
SUBTASK 72-32-86-360-051 Prepare the Mating Surfaces for the Cold Curing Silicone Rubber Compound
Refer to the SPM TASK 70-38-02-300-503.
Apply chromate conversion coating to the repair surfaces, if necessary.
SUBTASK 72-32-86-230-053 Apply the Surface Protection to the Rear Fairing Assembly

CAUTION
DO NOT EAT ANYTHING OR SMOKE AT LOCATIONS WHERE THESE MATERIALS ARE USED.
CAUTION
AFTER PREPARATION THE MATING SURFACES MUST BE FULLY CLEANED AND MUST NOT BE TOUCHED BY HAND, TO PREVENT CONTAMINATION.
CAUTION
DO NOT APPLY THE PRIMER TO THE MATING SURFACE OF THE STRIP SEAL BECAUSE THE SILICON RUBBER IS WEAK IN THE BOND STRENGTH IF YOU APPLY THE PRIMER.NOTE
The primer must be applied immediately after the mating surfaces are prepared, It is cured at room temperature by touching to moisture in air.If the parts are not used immediately, after the primer is applied, they must be kept in polythene bags, but for no longer than 24 hours.Apply a thin layer of primer only to the prepared mating surface of rear fairing. Dry in air for 30 minutes.
