You should replace the radiator and the thermostat and flush the coolant system . Rigging the radiator is just going to lead you to more overheating down the road.

Once you fix the cooling system problem, then you can tackle the drive-ability issue.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

You cannot glue those radiators. All that will get you is a blown head gasket or worse. You have probably plugged everything up with the stop leak now anyway. You've made your problem twice as bad as it was.
