Have you ever used it? It works well for getting that final bit of seal. I put it in the ball sockets on WCJr. I used it in lieu of a header gasket on the Caddy engine in my Jaguar (which admittedly was a step too far).

No,I have never used it but I've scraped plenty of it off where someone else though it would seal an exhaust leak. I fix things right so I don't have to use goo to half ass it.
Two-bolt flange, but perhaps they have something similar for 3-bolt applications. These replaced the rotted flanges on my so-called "stainless steel" Edelbrock shorty headers.
The two long bolts clamping the donut are in fact way TOO long. They were what I had on-hand at the time. I used some plain ol' 1/2" hex nuts as spacers to take up the extra length, and then double-nutted the assembly to prevent loosening. Ugly as sin, but also nicely-invisible unless you're under the truck.
Permatex is big on promoting their "high temp" orange RTV Silicone; including it's 750-degree "intermittent" temp limit. I've asked Permatex reps twice about what is considered "intemittent" use (how long before it's considered "long-term" use) and what the long-term temp limit is. Both items are TOP SECRET and they WILL NOT ANSWER ME.
Normally I despise the stuff, but there's no sealing that bigass gasket for the two exhaust pipes/two catalytic converters on the Vortec engines without heroic measures. So when I need an exhaust sealer, I use Waterglass in the form of Permatex Muffler and Tailpipe Sealer, good for up to TWO THOUSAND degrees.
