Do I need to get a metal gasket from my local Porsche dealer or use the paper gasket that came with the pump? And if so, what sealant do you all recommend for the paper gasket?

BACKGROUND
I’m replacing my water pump and thermostat. My 1999 Boxster Tiptronic with over 301,000 miles developed a massive water pump leak. I purchased a low temperature thermostat from Pelican parts and it came with a metal gasket. My new water pump came with an old fashion paper gasket.
I’ve read the technical articles on replacing a Boxster water pump on the Pelican Parts website and read the about the procedure in my Bentley Service Manual and 101 Projects for Your Porsche Boxster. I don’t believe I read anything about using gasket sealant. But I’ve changed many water pumps on GM & Ford small block V8s and V6s. And each time the pump came with a paper gasket and I used sealant.
I changed both radiators in February. My wife says I should have changed the pump when I changed the radiators

Sounds like you need to listen to your wife! What are her thoughts on the water pump you bought? Hopefully you bought a Pierburg. You are going to lose all your coolant you just put in after the rad install, but consider it a good flushing. As far as the gasket, toss the paper in the trash and buy the metal gasket. You don't want to have to clean old gasket sealer during future pump changes. At 300k I doubt you have the original pump but pay attention to the gasket cutting instructions if you do! And if you do DAMN! Congrats on the big 300k!!!
