I thought those cheap carbon paste tubes from the auto parts store were a total scam.

A customer brought in a creaky carbon seatpost that wouldn't stay put, even with a ton of torque, and I grabbed a tube of Permatex 80078 I had lying around as a last resort. After cleaning and applying it, the post held solid at 5.5 Nm with zero noise, which completely changed my mind about using non-bike specific pastes. Has anyone else found a good off-brand carbon assembly compound that actually works?

So my old bike was the real scam then?

Honestly, I'd worry more about the bolt itself stretching with anti-seize.

That Permatex 80078 is just a high-temp anti-seize, right? I'm curious if you've tried it on a stem or crank where the torque spec is much higher. I'd worry about it breaking down under real load.
