That time I called BS on a $15 tube of boiler gasket sealant and ate my words two weeks later

I was working on a flange joint on a 150 PSI steam line outside Toledo and the old timer on site swore by this cheap Permatex stuff for high temp jobs. After I fought with it for half a day and the thing held pressure like a champ with zero weeps, I had to admit I was completely wrong. Anyone else got a product they were dead sure was snake oil but it actually pulled through on a rough job?

Nah that old timer knew his stuff, glad you ate crow on that one.

So what was the exact Permatex stuff? I've had mixed luck with their high temp gasket makers on steam lines, but I'm curious if there's a specific one that actually holds up at 150 PSI long term. I'm always looking for something that doesn't turn into a crusty mess after a few months.
