JB Weld 8297 HighHeat is a hand mixable epoxy putty stick specifically formulated to bond and repair materials that will be exposed to high temperatures in automotive and industrial maintenance applications. It cures to a tough, hard bond with little to no shrinkage. This industrial-strength product outperforms conventional epoxy putties at high temperatures and sets in 1 hour at room temperature. After 8 hours, it can be drilled, tapped, machined, ground, filed and painted. HighHeat is rated at a tensile strength of 800 PSI and cures to a machine grey in color. It is able to withstand continuous heat exposure of 400ºF and intermittent heat exposure to 550ºF

1. Cut: Remove required amount of putty.
2. Mix: Thoroughly knead putty with fingers to a uniform color.
3. Apply: Press putty firmly to the surface to be repaired.
*For best results use a detergent or degreaser to first clean the surface, then roughen the surface with a file or coarse sandpaper to provide the best repair. Apply only to clean/dry surfaces.
Set Time One Hour. Cure time 8 hours.
Seems to perform well. Easy to use.
Have never had a bad experience with JB Weld products. First experience with this particular one. Used during repair of spark plug thread repair on a 2001 F150 5.4L (with a Calvan insert). Wasn't too sure about the application, as it almost didn't make sense to use a clay-like substance on threads of an insert. I would suggest applying on a warm day if possible,as it was rather chilly when I did..which I believe made it a little less pliable. It has held really well thus far.
Typical JB Weld - fantastic products! I use them all the time and have never, ever, had a problem. Keep up the great work - JB Weld!!!!
