But for gaskets that I know I might need to reuse, say like on a raw water impeller cover, I seal one side of the gasket with Permatex #2 and lube the other side of the gasket with Super Lube.
That way the Permatex side stays stuck to the impeller cover while the Super Lube side comes free without tearing the gasket.
Just my penny's worth.
I use Hylomar, it was specifically developed by Rolls Royce for surface mating gaskets.
Use evenly & lightly on clean dry gasket surfaces, pay particular attention to torque settings and order of tightening.
I've never had a failure yet.
