There seem to be two main problems with the 3 solid iron Sun theories.

1. How can the Sun have a solid iron shell, whether 500 or 5,000 km below the top of the photosphere, and still have differential rotation at different latitudes?

2. How can a solid iron shell maintain charge separation that allows electric discharges to arc from the iron surface into the solar atmosphere and then back down to the solid iron shell

 

1. The Earth has differential rotation at different latitudes. Its called the "global winds". http://avhs2.ednet.ns.ca/staff/wile/Global%20Wind%20Patterns_files/image002.jpg Earth has a solid rocky surface. All active stars have differential rotation (weather), unless they are dead and possess no atmosphere similar to the Moon.

2. The Earth has a solid rocky exterior and also has electric discharges that arc from the surface to the atmosphere and back down again. Its called lightning. The lightning on the Sun is constant, as its atmosphere is almost completely ionized.  

Most importantly, if we want to understand the Sun, we must study the Earth. The Earth is an evolved star and resembled the Sun earlier in its evolution.
