Review Summary

The product is a versatile and effective sealant that works well to stop fuel leaks, seal gaskets, and create tight seals on various automotive and mechanical components. Customers reported it was easy to use, though some noted it had a thinner consistency than expected. While a few mentioned it was not fully fuel resistant, the majority found it to be a reliable sealant for gas-powered equipment across many different vehicle and machinery types.

    It says fuel resistant but be aware. I applied it under a sending unit in a boat fuel tank and it just turned to sloppy goop after I let it set up for two days. Permatex makes a good product but calling this fuel resistant is not correct.
