Pros & Cons
Pros
Solved my problem. It is magic.
Product is perfect! As advertised. Another excellent product by permatex. Highly recommend this product.
Thicker than expected, but spreads well. Once it dries u almost need a prybar to separate it. A bit tricky getting out of the tube.
Cons
Didn't seal me up at all. Leaks like a sieve. Tube looks nothing like it's meant to, and the text is all messed up.
Highlights
Quality
Very quick shipping, the product works perfect as described, good seller, great!
I was liberal with the application and it did not seem to harm anything.
Price
Fair price, prompt delivery, performed as expected
Competitiveness
Used this to seal a 1930 model a ford oil pan/gasket.
Rebuilt a volvo 850 5-cyl engine using this stuff.
Worked just as well as the volvo brand sealant i used on the same job previously, but for a fraction of the cost.

It seals excellently but if you get a little extra it doesnt harden and clog oil and coolant passages in the engine
