In all fairness, I cannot rate this product since I have not used it as of this time. However, I am certain that it will meet or exceed my expectations. Presently, I am attempting to find a brass end cap fitting 3/8 inch with tapered NPT. Once I have found the fitting and sealed my fuel tank I will be able to use the sealant.

I used this to seal a crank case bolt on the top of the engine which was leaking oil. Works great. Smells like Proseal and is just as messy but a great product.

We used this to seal the crankshaft plug on my Piper Cherokee. A little goes a long way. Just make sure you mix it properly and you will not have any issues. Cheaper than Proseal and works just as well! Great Product.

First time I’ve used this product . Worked as advertised. Very messy stuff if you not prepared .

Good product. Mixes well. Could use a better method of getting the product out of the applicator
