I seal my frizzen with a mix of neatsfoot oil and beeswax, about the consistency of snowseal. Put a bead all the way around the pan and close it after priming, then smear a little tween the barrel and frizzen. I never seal the bore, got a borebutter patched round ball down there, I just keep the muzzle down. Never had any kind a hangfire...works well for me and it do rain here, about as much if not more than anywhere else! On my "other" guns, I do seal the bore with duct tape.
