I use that to seal Porsche engine
case halves. It stays nice & wet for a couple of hours to allow for assembly and becomes a hard plastic when deprived of air as described by the Jedi. The stuff that goops out of the sides wipes up easily. Loctite 574 is another, and Wurth makes one that is the same also but now I use the Volvo
stuff because I get 4 times as much for the same money
. That way it's inexpensive enough that I can use it on some of the more leak prone paper gaskets on these engines and transmissions and deliver leak-free rather than not very leaky parts
It's tough to clean off after assembly but it's way easier than fixing oil leaks
Don't use a lot, just enough for a thin coat on one side. It's made for precisely finished flanges so they must be very clean and smooth.
Volvo's number is 1161059. It's called Chemical Gasket
, High Temperature in translated Swedish.
It even smells good.
