On my 05 Trailblazer 4.2L the;) water pump paper gasket from the auto parts store failed and ordered a oem metal gasket waiting on it in the mail.

My questions / myth maybe:

On the water pump paper gasket type I see post all over the internet stating you should never put sealant on the the paper gaskets? (Maybe that was my mistake)

As far as the metal water pump gasket should I put sealant on it or not?

SPARINGLY - use some RTV - probably the best would be Permatex 22071.

If you use too much and it oozes inward, it usually winds up in the radiator, plugging the cooling tubes.
