<font face="Comic Sans MS">What part of your exhaust is it on? A MIG welder or torch and brazing rod might be better depending upon where on the exhaust it is. [img]/wwwthreads_images/icons/crazy.gif[/img] </font>
I've done it with mixed results. it worked great on my old ranger a long ways away from the engine. i used it on a jeep wrangler and it burt, and smelled like the most foul;d rotten fish mixed with fecal matter from a 23yr old goat all mixed up in some sort of a chemoical docomposition goo. it smelled nasty. check your parts store for smomesort of high heat epoxy. usually sits right on the counter when you check out

"...smelled like the most foul;d rotten fish mixed with fecal matter from a 23yr old goat all mixed up in some sort of a chemoical docomposition goo.." Now thats rotten if I've ever heard of rotten.
I tried it as an experiment. Did not work out. I had a cracked exhaust manifold on an old 283. If the crack is not close to the head, it might work better. It did not hold up to the heat, but works great on other things.
Rhino, I just got my POR 15 catalauge today, and they have some stuff in there you might be interested in. Go to http://www.POR15.com and look for the stuff called <font color=red>Fire Seal 2000</font color=red>. Sounds exactly like what you want.
Well guys, I broke down, bought a Miller 150 MIG welder, and did it myself. I've been wanting a MIG for quite some time, to do my own fab work, as well as little stuff like skid plates and exhaust. Also works well for Bike frames, etc. I know it sounds overboard, but it'll pay for itself in no time. BTW, I also bought a "pony tank" with sheilding gas. Thanks for the advice!!]
I went to POR-15 website and got that catalog too. They have a lot of stuff! And if the other stuff works like the POR-15, well that would just be dam* cool.[img]/wwwthreads_images/icons/smile.gif[/img] We should start a post to relay information on the other products that they have. And so people who use them could tell other people how they worked. Anyway, just bs'in.
