STOP LEAK head gasket remedy,is this effective?

[lowslowbenz]

Anyone tried using it already as a temporary fix for leaks in head gasket?

If head gasket leak is the main culprit (proven, tested, confirmed), then the only fix for that is a new head gasket.

if you're stuck somewhere in the boondocks, it may work but I'd rate that possibility to a slim 10% over a 100.
