### ⭐⭐⭐⭐⭐ Very good product

Excellent,would buy again

### ⭐⭐⭐⭐⭐ No leaks where I used this!
*by M***S on 9 January 2025*

Used this to seal the differentials on my Land Rover - works perfectly, as I expected it to do. It's specifically designed to seal compartments containing gear oil. I used Blue Hylomar - a good sealant, but not specific to gear oil sealing - on some other gearbox components & I do have a few small leaks. Well, it's a Land Rover, they do leak - but I think this Permatex Gear Oil sealer is most likely to minimize them! Recommended!
