To radiate what?

The radio waves.
Do you agree with Jim: "Insulated antennas work just fine."?

"Just fine" may means enough.
But I am interesting in: "What is better: bare metal or insulated metal?"

Depends entirely on what the insulation is composed of!!

Only if the insulation is infinitly lossy or infinitly thick.

even infinitely thick insulation allows radiation.

If the insulation is infinitely thick, there is no outside of the insulation
where radiation can occur.

But, yes, there will be radiation inside the insulation.

Air is an insulator.....

And yes there is radiation in the air as I said above but the air is not
infinitely thick.

Like vacuum. But there are ions and free electrons.
In solid and liquid insulators no free electrons.

Does solid insulation makes the radiation weaker or stop it?
