Stag is best. However I've used Loctite 515 or Permatex aviation gasket cement successfully.

Doc, I was told stag is vey susceptible to the modern coolants we use these days. I have used loctite 515 with success.

I used Stag on a leaking plug about 3 years ago and it's still holding OK, with corrosion inhibitor in coolant.

I put Stag on the core plugs in an engine I did 10 years ago - still not leaking!
Everything else in the mini however....

I used a dab of the mercury non hardening gasket sealer on mine about 14 years ago. No leaks!

Aviation sealer or Wurth pipe seal. Never had any issues with either.
