4.0 out of 5 stars Seal broken, showed up dried out.
Reviewed in the United States on May 1, 2022
I was able to use less than half of what arrived. The seal was broken which let air in. Nothing leaked out but there was a hard layer under the seal that was unusable. Once I broke that out there was a mixture of hard and soft product. The amount barely covered what I needed so it was upsetting to not have 100% of the product at my disposal.

The product itself is great. I was able to cover the hole in my exhaust, smoothed it out and awaited 24 hours. It is now hard as a rock and I no longer have an exhaust leak. I will buy this product again.
