Does JB Weld handle high heat?
I've had an exhaust rattle for a while. I thought I fixed it a couple weeks ago by riveting the heatshield above the cat back on because it was loose. For whatever reason, the rattle went away for a day. Then it came back sounding exactly the same. I figured a rivet popped out. I got under it today with the revit gun, but they were in tact. So I did some banging around and found that the heat shield on the cat itself has come loose. I wrapped the loose end with aluminum tape and some bailing wire. It stopped rattling, but I know it'* not a permanent fix. If I use some JB weld on it, will it hold?
