    Drifter, would love to know what kind of manual would make a recommendation like that….Some of that anti-seize stuff can actually promote corrosion when mixed with the aluminum and salt water. Yes, I realize that the anti seize company does make aluminum compatible products, but they would have little value when it comes to sealing a head gasket.
    The best stuff to use when sealing head gaskets is the OMC/Merc gasket sealing compound. Using the gasket sealer around the outer edges of the head gasket is all that is needed, this will not help seal a fault in the cylinder to head surfaces, although it surely won’t hurt to apply there as well.

    I’ve wondered if the copper loaded anti-seize is really OK to use with aluminum. Is that what we are talking about here?
