ยง  733.  Warrantor  liability for authorized aftermarket rustproofing;
  notification. 1. It shall be unlawful for a warrantor to include in  any
  warranty  agreement  a  clause that purports to limit a buyer's warranty
  protection on the basis that the buyer has, or may have, a  claim  under
  an existing warranty.
2.  It  shall be unlawful for a warrantor to fail to notify a buyer in
  writing within ten business days of inspecting the buyer's motor vehicle
  for rust damage whether the warranty claim will be allowed or denied. If
  the claim is denied, the specific reasons for the denial shall be stated
  in writing.
3. It shall be unlawful for a warrantor to fail  to  honor  a  buyer's
  warranty  claim  on  the  basis  that  the  aftermarket rustproofing was
  applied improperly, if such service was provided by a person  authorized
  by the warrantor.
4.  Nothing  contained  in  this  section shall be deemed to prevent a
  warrantor from refusing to honor a warranty claim based upon the failure
  of a buyer to comply with provisions of a warranty with respect  to  the
  proper care and maintenance of the aftermarket rustproofing.
