b. C o r r o s i o n .In hot, damp climates, corrosive action will occur on all parts of
the materiel and will be accelerated during rainy seasons. Evidence will appear as
rust, paint blisters, mildew, mold and fungus growth.

Protect cables and terminals by spraying with ignition insulation compound.
4-58 MAINTENANCE AFTER FORDING.
a. General. Although materiel unit housings are sealed to prevent the free flow
of water into the housings, it must be realized that due to the necessary design of
t h e s e assemblies, some water may enter, e s p e c i a l l y d u r i n g s u b m e r s i o n . T h e f o l l o w i n g
services should be accomplished on all materiel which has been exposed to some depth
of water or completely submerged, especially in salt water. Precautions should be
t a k e n as soon as practicable to halt deterioration and avoid damage before the
semitrailer is driven extensively in regular service.
