I'm waiting till the end of the break in period. If there is a problem, the builder says to contact him and he has a fix for the leak. The leak has slowed but not completely stopped. We'll see how things turn out.
I guess you kinda need to play along with the seller for warranty, however sounds like you’re hoping for a miracle and avoiding the reality of it. Freeze plug sealant doesn’t cure more or expand or migrate over time.
the only way a leak path would seal is via radiator sealant, a high concentration of minerals in pure water “clogging” the leak or divine intervention.

Bummer, man.
