## Discrepancy

ALL OF THE DOPE FILM DELAMINATED FROM THE CECONITE 102 FABRIC.  AFTER SEVERAL PHONE CALLS, IT WAS DETERMINED THAT IMPROPER APPLICATION METHOD WAS USED.  THE RANDOLPH DOPE PROCESS REQUIRES THE USE OF RANDO PROOF PRIMER FOR THE FIRST TWO COATS ON CECONITE FABRIC AND THE FIBERS OF THE FABRIC MUST BE COMPLETELY ENCAPSULATED.  AFTER ADDITIONAL CALLS, IT WAS DETERMINED THAT THE FACTORY OMMITED THE RANDO PROOF PRIMER STEP AND FAILED TO ENCAPSULATE THE FABRIC FIBERS RESULTING IN THE DELAMINATION OF THE DOPE FILM.
