[Mg-t] Making a gasket

[JohnD]

I can't get the joint at the bottom of the thermostat housing to not leak.
First I used a paper gasket. Then paper and a light schmear of RTV on either
side.
Then I cut a gasket from what looks like neoprene embedded cork gasket
material. Put a bead of RTV on both surfaces, finger tightened and let set
up over night. Then wrenched it down the next day. Still leaks. I have
cleaned up both mating surfaces and I realize that the engine side is not
entirely flat. So, what to do if I need to rest drive tomorrow? How about if
I cut a gasket out of a piece of rubber, perhaps a bit thicker than an inner
tube? Or maybe another neoprene-cork gasket but not tighten the two nuts so
much?
All suggestions welcome.  Thanks!
