what gasket goo do people recommend for a rebuild

I am about to put a waterboxer back together and want to know what brand/type of gasket
goo people use.Do you apply it to all sealing surfaces/gaskets. Some people have been using
the same sealing solution on the "O" rings around the water pump and associated pipes as
well. Is this necessary? I thought the idea of an "O" ring was to move and expand with the
pressure in the pipes. This would not be possible with extra gasket sealer getting in the way.
Or does it add a second seal by forming an additional gasket around the outside and inside
lip of the water pump housing. There was also a posting about a week ago of a member in
Perth who was selling some reco heads,are they still available ?
Thanks.

Use rubber grease on the O ring.
