CORROSION PREVENTION AND CONTROL. a. Corrosion  prevention  and  control  (CPC)  of  Army  materiel  is  a  continuing  concern.    It  is  important  that  any corrosion problem be reported so it can be corrected and improvements can be made to prevent the problem in the future. b. While  corrosion  is  typically  associated   with   the   rusting   of   metals,   it   can   also   include   deterioration   of   other materials,   such   as   rubber   and   plastic.      Unusual   cracking,   softening,   swelling,   or   breaking   of   materials   may indicate a corrosion problem. c. If a corrosion problem is identified, it  can  be  reported  using  an  SF  Form  368.    The  use  of  key  words,  such  as "corrosion,"  "rust,"  "deterioration,"  or  "cracking,"  will  ensure  that  the  information  is  identified  as  a  CPC  problem. The form should be submitted to the address specified in DA Pam 738-750. 1-3
