RB Welch/Core Plug Sealant?

[RB25Detonator]

What sealant do you guys use on welch/core/freeze plugs on your RBs? I'm in the process of building an RB30/25 and I can't seem to find any answers on here. I have bought brand new brass welch plugs. Apparently you have to use a special silicone sealant? I read somewhere on here that someone said loctite 504. Then I read somewhere els on the interweb (on other engines) that someone said permatex no. 3, and stag. LS motors have special ones that they buy from GM i think.

I bought a nissan gasket kit and got nissan fluid gasket which i'll be using on the water pump. Do you also use it on the oil pump (+gasket) and oil pan?

Don’t use the Nissan stuff on the oil pump gasket 

I’ve always used stag on Welch plugs
