Does a great job when applied to both sides of a gasket and also to both matching surfaces of and engine or transmission component. Make a leakproof seal and help to make up for imperfection in the fitted part surfaces. It does not harden and is relatively easy to separate the engine components later on, compared to say, RTV. A paper or fiber gasket isn’t likely to survive, though, and will need to be replaced.
I found that it’s necessary to check the bolt torque again after the Hylomar has setup for a while. It does squeeze out and compress and invariably the bolts need a small snugging.
Good stuff.
EDIT 2/6/2021: Product solidified and was useless after a year and a half. I've had other sealers last 4 years without issues before. Won't buy again due to the high cost and lack of storage capability. I bought a cheaper version made by Permatex, and it works just as good, without the short storage issues.
I just completely replaced the fuel system and have used this to seal fuel line threads and fuel pump gaskets.
I've also used this to seal the threads for the oil pressure sending units.
This Hylomar Blue works well. No leaks. Does not harden. Can use it for gasoline and oil.
I've got a bunch more parts coming and I'll be using this during the entire restoration.
I recommend it.
