My shop's switch to fiberglass for boiler patches has me looking back.
It feels strange to use composite stuff where we always welded steel, and I'm not sure if it's a good change.

Yeah nothing says industrial strength like slapping some fancy plastic on a boiler, right (I mean, what's next, fixing a cracked frame with bubblegum?). It just feels wrong, like patching a cast iron skillet with a band-aid. Sure it might hold for now, but you just know the real fix is coming later (probably with a lot more cussing and a bigger bill). Honestly, waiting for the day a big vibration just pops that whole patch off like a cartoon.

Agree with phoenix_lopez3 on the weird feeling. It just lacks that solid, permanent trust you get from a proper weld. A fiberglass wrap feels like a quick cover up, not a real fix, even if the specs say it holds. My gut says you can't beat melting metal together for something under that much pressure and heat. The old way just felt more honest, like you were leaving it better than you found it. This new stuff feels like waiting for the next problem.
