Default Flathead V8 radiator

Two upper hose brass connections, sweated onto the brass upper tank.
One of them looks like the photo. Weep/seep..... whatever you want to call it.

I'm having to top the radiator off after every drive. (Whether the water level is above or below the fitting, same result) I'm assuming the water level needs to be at or slightly above the top of the core.
My gut reaction is I should try to re-solder the problem fitting.
Water temp may get to a blistering 165-degrees at the maximum.
No water in the oil pan, no water out the exhaust and none on the ground. Water is going somewhere.

Could I be losing 1 quart of water out the leaking seam at the connector? It isn't visibly "wet." You can see the evidence though.

Anyone ever solder something like this radiator fitting? (acid core solder)
Historically, my past results haven't been too impressive.
I may try it anyway as I loath taking the radiator out of this vehicle and then having to re-establish the water level after you reinstall..... which seems to take about 2 months.
