(b)
Install fasteners (stainless steel bolt and dimpled washer)
(c)
Measure the resistance.
1) Maximum resistance shall not exceed 300,000 OHMs.
(d)
Touch up finish.
NOTE: Do not apply anti-static paint to flame sprayed
____
aluminum.

Apply the corrosion preventive compound, MIL-C-11796, to the flanges on the fairing which touches the structure.
S 374-013-B00
(8)
Apply the sealing compound, BMS 5-26 or BMS 5-95, to the flanges on the fairing which touches the body skin.
S 374-014-B00
(9)
Apply the corrosion inhibitive compound, BMS 3-23, to the area on the structure and the body skin which touches the fairing.
S 424-015-B00
(10)
Install the fasteners which attach the fairing to the structure.
NOTE: Make sure you install the stainless steel bolts and
____ dimpled washers at the same locations on the fairing panel as they were prior to removal of the panels. Installing different hardware in these locations may result in unacceptable electrical bonding.
(a) Torque fasteners to 25-35 lb. inches (2.8-4.0 Nm).
