Reviews

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.
