Default copper headgaskets, sealer?

What is your favorite sealer for the water passages when using copper head gaskets?

Some copper gaskets already have a sealer on them, But for the ones that do not, I use Coppercoat from Permatex.

Default Gasket sealer

I've had good luck with Hylomar gasket sealer. It was recommended by an area performance engine builder. There are plenty out there. I would use coppercoat if I couldn't find Hylomar.
