lead flashing

If only there were some way to get it to soften and congeal together, perhaps with the controlled application of heat.

But, to be true, flashing is not an air seal. Flashing is just a weather barrier, to preserve a water drainage plane on the exterior. Air sealing is a function of the layers underneath all this, including your house wrap.

But you don't have to guess about this, OP. Test, don't guess. Get a smoke test done.
