Works great for muffler repairs
Used this J-B Weld MufflerSeal to fix a small leak in my car’s muffler, and it worked really well. The cement is thick and easy to apply, and it sets up quickly. Once it cured, the leak was completely sealed and it’s holding up perfectly even under heat and vibration. Definitely a good, affordable solution if you need a quick muffler repair without replacing the whole part.

Good stuff and thick enough to stay where you put it
Due to operator error I had a badly damaged exhaust pipe on my tractor. Rips and holes in the steel exiting the muffler. This stuff has tha consistency of thickish toothpaste and won't fall though a pencil size hole. Saved me from a whole new muffler. Zero complaints!

Works great if you follow instructions
JB Weld makes a good product. Follow prep instructions and you’ll have a solid seal that lasts if you don’t prep it won’t stick as well and can flake off. Let it cure before driving or running the engine.

Very effective
After I used a wee wheel to clean away any rust from the exhaust leak , I applied this cement and smoothed it with my finger. It held nicely after several hours and works well. Hope it holds up for a while.
