"Gorilla snot" is what we called 3M weather-strip adhesive and no it is no good for sealing anything with heat applied. It is good for holding gaskets in place until assembled. The best stuff for making liquid gaskets is GM black RTV that is O2 sensor safe gasket adhesive and maker. This one works stand alone is designed for all automotive applications, and is gas and oil resistant. The 3M will eventually get hard crack and leak. The Permatex will not. 15 years of auto repairs proved that one for me working in the profession. It has also become the standard from the assembly line on virtually all rear wheel drive axle cases, valve covers not using rubber gaskets, the ends of the intake gaskets on V6 & V8 engines, and much more. Good building....
