Anyone here used this product before? Or have any good experiences with any similar exhaust putty?

Don't know how it compares but we used to use GunGum often coupled with a bean tin and a couple of jubilee clips. The Gungum always outlasted the bean can and jubilees.
Just remembered there was also a white cement that went in the manifold to exhaust pipe join if it had one of those ring gaskets and a loose collar on the pipe.

Well, it arrived in the post yesterday so we went down the yard after work and I've applied it to the lorry exhaust. It needs to be left for 24 hours to harden so will head back down there to run her up tonight.

Just going back to this older post, just to say that the J-B Weld has actually done very well. It cures so well and you can really push it into hard to get to places.

I would highly recommend this and we will be using it again if needed.

Good to have some feedback on stuff like this.
