PRODUCT WAS EXCELLENT,PRICE WAS VERY REASONABLE. THERE WAS NO HARDENER INCLUDED IN PURCHASE,THIS WAS LIKE PURCHASING SHOES WHICH REQUIRED SHOES LACES BUT NOT INCLUDED.AFTER BUYING HARDENER & SHIPPING WAS NOT THAT GREAT OF A PURCHASE AS PROMOTED TO BE.VERY DISSATISFIED & TURNED OFF BY PURCHASING IN FUTURE FROM AMAZON.
