Section 2--605. Waiver of Buyer's Objections by Failure to Particularize

(1) The buyer's failure  to  state  in  connection  with  rejection  a
  particular  defect  which  is  ascertainable  by  reasonable  inspection
  precludes him from relying on the unstated defect to  justify  rejection
  or to establish breach
         (a) where the seller could have cured it if stated seasonably; or
         (b) between  merchants when the seller has after rejection made a
             request in writing for a full and final written statement  of
             all defects on which the buyer proposes to rely.
    (2)  Payment  against  documents  made  without  reservation of rights
  precludes recovery of the payment for defects apparent on  the  face  of
  the documents.
