J-B Weld 8297-DEU HighHeat, Heat-Resistant epoxy Metal Putty for All high Temperature Jobs, Gray, one Size

Used this stuff before works brilliantly you must give it at least 24 hours to set you will not be disappointed I used on a old parkray fire couldn't get a glass for the door used a steel plate and used this to seal the steel to the door it's still on 10 years later

Upto now it's working. I dropped my motorbike. And put an hole in the engine casingApplied jb weld on it .and it's working. Saved me alot of hassle of taking fairings of and replacing gaskets. Ide use it again

My favourite long lasting get-out-of-jail repair product. Fantastic stuff.

I have a small river boat which uses a heat exchanger to cool the engine. The heat exchanger is made from cast aluminium and has a brass filling nozzle with a pressure cap, much like a radiator cap. Over time the radiator nozzle developed a small leak at the interface with the heat exchanger depositing coolant in my bilges when the engine was running. I bought a new filler nozzle and, with the help of a blow lamp, set about removing the existing item. Once the opening was cleaned up I used this product to bond the new nozzle in place. Curing in the relatively low ambient temperatures was slow so I taped everything in position and let it be for a full 48 hours. After this time, the bead of adhesive I could see and touch around the nozzle was as hard as bell metal as was the residual amount mixed that I had retained. I topped up the system with coolant and have since made several long trips in the boat without any sign of leakage. An excellent product which appears to be doing exactly what the manufacturer says it will.

Easy to use, good adhesion. Good range of applications.

This is a useful epoxy for all sorts of jobs where higher temp is needed.

Used for mending a fitting on a lawnmower engine. Area gets very hot and fitting remains solid. Not sure how well with works over a long period of time but does as advertised.
