(1). In rejecting goods, a lessee's failure to state a particular defect that is ascertainable by reasonable inspection precludes the lessee from relying on the defect to justify rejection or to establish default:
(a). If, stated seasonably, the lessor or the supplier could have cured it (section 2‑1513); or
(b). Between merchants if the lessor or the supplier after rejection has made a request in writing for a full and final written statement of all defects on which the lessee proposes to rely.
(2). A lessee's failure to reserve rights when paying rent or other consideration against documents precludes recovery of the payment for defects apparent in the documents.
