Clio 172 Waterpump gasket - nothing, grease or Hermitite blue?

Does the Clio 172 waterpump gaskets need any sealer? The gaskets fixed well to the pump face so I assuming yes.

Its well fixed so was going to use the Renault blue stuff - is that right?

I wouldn't use hermetite for anything ever personally. But i would use a very light smear of sealer on the waterpump gasket surfaces as it'd be a pain if it leaked
