TM 10-3930-669-20 While corrosion is typically associated with rusting of metals, corrosion can also include deterioration of other materials, such  as  rubber  and  plastic.    Unusual  cracking,  softening,  swilling,  or  breaking  of  these  materials  may  be  a  corrosion problem. If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Deficiency Report.  Use of key words such as "corrosion, rust, deterioration, and 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. Section II.  EQUIPMENT DESCRIPTION AND DATA 1-9.   EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
