What are you using?
I was going to use the age old method of sealant and silk thread but found the old POB #4 sealant is no longer available. I think I found the correct new sealants(for use w/silk thread) but after a search have decided on simply using a bead Loctite 518. I know the Lycoming SB says 515 but Loctite says 518 is best for AL and I found several mechanics suggesting 518.
