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!

Used it to fix my dryer air filter which broke as a nut had come off. Was not sure how it will dry but it became rock solid. No effect of heat on it after drying. Will see how it stands after multiple dryer sessions. Will update.

Dose what supposed to do, used for temporary fix on exhaust system, held up until pipe was replaced, no complaints.
