Handy to have in the house or car.
This stuff is great and has gotten me out of trouble with a leaking exhaust. Sets hard as steel. Smells a bit initially but this goes away as it hardens.

Does the job it says it will!! Excellent!
Seems to be a fantastic product! I bought this after my car developed quite a serious coolant leak from a metal pipe part of the engine. Wanted to use it as emergency fix really, however it turned out so good that it has become permanent fix until I have the will and time to take the car to the garage. I have filled the instructions to the letter and left it dry for 12 hours, just in case... I waited with this review for nearly two weeks to see the actual performance of the product... It hardened to a rock hard substrate and sealed the hole completely and reliably. Absolute bargain as well! I've put some before and after pictures. Can't recommend this enough!

Excellent stuff. Long term review.
Had a small hole in our hall radiator. I was skeptical to tell the truth. Hallelujah, it actually worked. Sealed the hole, no problem. Over a year now since I did the repair. Still no leak. Once the putty sets, it goes rock hard. Handy stuff to have in the tool box.Highly recommended..

Easy repair for exhaust and bracket
Had to purchase this as during an inspection under my car I found the exhaust mounting bracket had broken away from the exhaust.So after making up a ball of this I applied it to the arm and exhaust, the adhesion was very good with no messiness. The bracket held to the exhaust and I left the vehicle to sit for a day and then took it for a long drive and checked the exhaust which was still held in place so this has good strength and durability. Hopefully this will last!
