Oil sump: gasket or sealing compound ?

Hello people, a quick and simple question: does the oil sump needs a gasket or only a sealing compound ?
Thanks in advance.
 
Hylomar or aviation gasket #2 or #3 would be my choices, the #2 or #3 with the tread trick (lay a string of sewing thread in the gasket sealant, to the inside of the bolt holes).

Yours

Early MX5 also have a cast alloy sump up to an iron block, and they call for something expensive, but Permatex Ultra Grey has worked well for me.
