WHEN APPLYING THE FIRST COAT OF EPOXY OVER THE FIBER GLASS CLOTH, I MISTAKENLY USED ONLY HARDENER--NO EPOXY, ON A SMALL AREA.  I THEN USED ACETONE TO TRY TO GET THE HARDENER OUT OF THE FIBERGLASS & WOOD ON A SIDE BOARD.  SEEMED TO ALL COME OUT & FELT DRY.  I THEN RECOATED THE AREA WITH CORRECTLY MIXED EPOXY & HARDENER, & ALL SEEMED WELL.  WENT ON TO FINISH THE ENTIRE KAYAK WITH 2 COATS.  LOOKED GOOD & FELT HARD.  A WEEK OR SO LATER SEVERAL SMALL SPOTS IN THE FIXED AREA HAVE BLISTERED.  ANY INFORMATION ON WHAT TO DO NOW WOULD BE OF GREAT HELP.
