(g)
Do not apply or let corrosion inhibiting compounds get on insulation
blankets. These compounds decrease the water-repellent quality and
increase flammable quality of the blankets. If corrosion inhibiting
compounds get on blankets, refer to SOPM 20-41-05 for instructions.
(h)
Do not apply these compounds on interior materials such as cargo
liners. The compounds change the flammable quality of these materi-als.

CORROSION PREVENTION MANUAL
GENERAL INFORMATION
STANDARD PREVENTIVE MAINTENANCE PROCEDURES
(i)
Do not apply these compounds near engines, cowling, or related areas
of high temperature or where firewall sealant is used. The high tem-perature can cause deterioration of the compounds. Corrosion inhib-iting compounds can cause damage to the sealant.
(j)
Some corrosion inhibiting compounds dry tack-free and may cause
increased friction or sluggish operation between moving parts. Do
not spray these compounds on areas, such as exposed actuator rods,
that will come in contact with other surfaces.
(4)
Compatibility of BMS 3-23
(a)
As these materials are all usually hydrocarbons, you can apply a
different compound over existent corrosion inhibitors without bad
effects.
(b)
The compound can be used on fiberglass fairings and ducts if the tem-perature of the duct is not hotter than 220'F.
(c)
The compound can be used on bladder fuel tanks and fuel vapor barri-ers.
(5)
Cleaning before application of BMS 3-23
(a) The surface does not have to be extremely clear before you apply
these compounds. But you will get better joint penetration if you
clean the area first before application. Vacuum or wipe away loose
dirt or other unwanted matter. Then you can clean the surfaces where
necessary, with the usual airplane cleaning agents or solvents.
(6)
Application of BMS 3-23
(a)
Obey the precautions given in step (4) above and use masks or shields
to give protection to components. Do not apply corrosion inhibiting
compounds to areas which will subsequently be painted or sealed.
(b)
Statically ground the airplane per Chapter 20 of the Maintenance
Manual.
(c)
Before you apply corrosion inhibitor near batteries, electrical con-tacts, electrical connectors, or other components where there could
be a fire hazard, remove external power and put the battery switch in
the off position.
(d)
Let all primers or enamels cure for a minimum of 8 hours.
