Lab Metal has been around for a while in the industrial industry for metal repair. I have some and used it on occaision but not too crazy about it. It is a one part filler, and has to dry, rather than cure like an epoxy filler. The thinner smells like lacquer thinner as does the product itself. It skins over pretty fast and then the solvent has to evaporate out of it to reach max hardness. The surface has to be clean and oil free, and have a "tooth" to it to adhere properly. I have had better luck with JB weld.
To Randy's point I have only used the regular Lab Metal not high temp.

The material listed in the product sheet attached to this link is "HI TEMP Lab Metal" It is resistant to temperatures up to 1000 Degrees F. after curing, and retains a large portion of it's strength to that temperature.
It requires a heat cure of a minimum of 425 degrees F. for four hours after an air cure of 24 hours.
It most definitely is not intended for applications where JB Weld would be considered since JB Weld is good only to about 450 F. before turning to putty, and the 425 degree cure would not be good for most wood or plastics, or any aluminum products where dimensional stability is an issue.
This is good stuff but has very limited usage for most of our applications, but might be good for a muffler repair ect., but don't let your wife catch you curing it in the oven as the smell will fill the house for days. LL~ LL~ LL~
