(2) Use the terms “corrosion resistant,” “rust resistant,” or any other term of similar meaning to describe an industry product unless all parts of the product are of such composition as to not be subject to material damage by corrosion or rust during the major portion of the life expectancy of the product under normal conditions of use.
