To avoid injury, keep the corrosion preventive away from heat, wearprotective goggles and use in a well-ventilated area.CAUTIONThere are two types of water-displacing corrosion preventive compounds. Caremust be used to apply the correct compound. Failure to do so can cause loss ofcontinuity or moisture protection.(a)Pin contacts: Spray an even, thin coat of compound MIL-C-81309 over male pin area ofconnector.(b)Socket contacts: Hold connector with openings pointed slightly downward, if possible. Spraycompound MIL-C-81309 into socket openings. Wipe off any excess compound with a lint-free cloth.CAUTIONDo not use water-displacing corrosion preventive compound MIL-C-81309 on theexternal surface of an electrical connector. Compound MIL-C-81309 is too lightand will not give the protection needed to keep moisture out of the connector.(c)External surfaces: Spray a thin coat of water-displacing corrosion preventive compound MIL-C-85054 on all external surfaces of the clean connector set. Make sure the area where the connector set comes together iscompletely covered.(12) Installing electrical connectors.(a)Look at connectors for broken, missing or pushed-in contact before making any connections. Ifconnector is bad, notify supervisor.(b)When installing connectors on large harnesses, another soldier will be needed to help aline themating ends of the cable.
