J-B Weld 8297 HighHeat 500 Degree Epoxy Putty-2 Pack

This jb weld to repair my generator cylinder head exhaust port gasket area

Sent me the expired product which the epoxy outer Grey portion had become hard. The packing production and expiry details were torn off. Attached picture for the same.

WORKS PERFECT IF DONE CORRECTLY. WORD TO THE WISE WHEN USING 1ST - MAKE SURE YOU HAVE EVERYTHING READY PRIOR TO USING. 2ND - HAVE A PIECE OF SOLID FLEXIBLE WIRE AS WELL AS A PIECE OF METAL FLEXIBLE BENDABLE SCREEN OF SOME SORTS 3RD - PUT THE PUDDY IN YOUR HANDS TO DESIRED AMOUNT AND KNEED UNTIL MIXED TOGETHER THEN PLACE IT WHERE NEEDED PUSHING IT IN REALLY TIGHT AND WELL THEN WRAP YOUR SCREEN AROUND PART BEING REPAIRED, FOLLOWED BY THE FLEXIBLE WIRE, MAKING SURE IT IS REALLY TIGHTLY WRAPPED AROUND IT, FOLLOWED BY A GOOD SOLID AMOUNT OF THE PUDDY BLENED TOGETHER AS SUGGESTED HEREIN THE ABOVE. 4TH - LET IT SIT AND DRY FOR AT LEAST 24 HRS PRIOR TO USING OR MOVING WHATEVER WAS JUST REPAIRED. HOPING THIS HELP! BLESSED BE!

Easy apply and need 24 hours to get hard. My repair job has been done almost 2 weeks. It works for me, but I dont know how long it will last.

This is a great product from a functional point of view. The only on site problem has to do with cutting the desired putty out of the protective plastic surrounding the putty mix. Cutting the plastic is troublesome and removing the plastic from the putty once cut is troublesome.
