Well...at this point I'm not sure if I want someone to hammer on the chimney
to crush the new cap. I sealed it for now with a roof sealer - the kind
that's applied with a trowel.

At this pace I will be looking at a new cap in year, I suspect, so would
like to prepare by learning what mortar works. OTOH - who knows after the
one crack relieves the tension, it may last for a while.

Who cares what formula he used. Get him to replace it. You wanted a new
cap not new cracks. Or was his warranty good only as long as you could
see his tail lights...
