Great Product
This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Worked perfect did not smoke on the stove
I got this to glue bumpers into a stove top grate. Easy to use, worked great. Did not smoke or anything and weeks later the bumpers are still holding. Saved me lots of $$$ as the tech said $200 each for the grills, and there were 3. LOL, it costs me this glue and $11 for the bumpers.

Worked Great for my smoker exhaust!
Bought this to seal the gap around the exhaust pipe on my Oklahoma Joe’s offset smoker and it works great! Make sure that if you’re planning on using your finger to spread it that you wear a latex glove or some other type of glove.
