Thermostat Housing

Well this will be the third time I am trying to fix a coolant leak from the thermostat housing. Since I am going to have it apart I figured I would replace the stat with a 180 degree, same as what I had previously. Got it from Advanced Auto and its in a Car Quest box and says made in Israel......How awesome is that? Anyways hoping the third time is a charm. Just to clarify the correct way to install it's gasket then thermostat then housing? I'm trying the permatex made especially for this application.
