water can

Sorry if I'm bothering you with this, but I want to learn from the experts in this forum...

I'm remodeling the water can from scratch. It looks like if I do not follow the sphere method, there is no continuity in the separate surfaces. I followed the cone method, and connected the bits with the blend command.

As you can see from the first screenshot I'm posting when I export the partial model (OBJ) there is no continuity. Even when I import in Max it looks separated, because of the faces that have been created (look at the second screenshot).

Is there a way to connect the separate pieces in order to get a completely smooth surface?
Thanks
Mark
