Sealant question for P gasket and waterpump gasket

Hi everyone. I need to change my P gasket and waterpump (and gasket) on my 300tdi.

I’m a little confused on which gasket sealant I should use on both these gaskets I need to fit. I’ve seen reference to using Hylomar, Hylosil and grease on my youtube searches. I’ve used Locktight whilst fitting coreplugs in the past but can’t remember which particular product i.e. which Locktight product number.

Can someone please confirm which sealant (or sealants) I should be using for each of these gaskets?

Thanks.

Iirc they are the metal/tin gaskets? if so dry is the way, unless things have changed?

I used a thin, even coating of Blue Hylomar (thinned with cellulose thinners and applied with a small brush).
I have also used silicone, both to good effect, both lasted for years.

+1 for Hylomar Blue
