What grease should I use to reduce seepage from loading tap leak?

[Dornfelderliebe]

I think the idea behind thick damping grease is that if the tap is fairly good, the thin layer of grease will stick like *** to a blanket and form a seal. If the gap is too wide it will get blown out as mine did. With electroplating will need to lap the tap to produce a perfect and likely more permanent seal. I shall to lap it with 1000 grit wet& dry (dry at 1st) and through trial and error attempt to make a perfect seal. Even then I will reassemble with minute amount of Nyogel just to act as a lubricant.
If the seal was so tight that it pushed all the grease out upon reassembly , I would expect the tap already to make a good seal
