No. Its definitely not JB Weld. The 500F was memory, could have been much higher. It's recommended for mufflers, catalytic converters, radiators, etc., so it can definitely withstand any temperatures or pressures that the oxygen sensor is subjected to.

It has the consistency of Mastic or putty with an inner and outer core. The inner core is black, and the outer core is greyish. You knead it in order to intermix the two layers. You then have a window of 4 Min to apply it. After that it starts to set and is cured 20 Min. It can even set underwater, and is impervious to all chemicals and fluids found in a car.

Its available at the Wall-Mart automotive section, but I am sure also at most hardware store. Sorry I don't remember the name, but you should be able to find it easaly by my description.

By the way, this stuff has never failed me, and it has always worked where JB Weld failed. Just make sure that it has a relatively clean surface to stick to, and that you knead it well.
