Matt,

I recently made a couple of toroids out of the semi-rigid aluminum duct
material.  I did not cover them with aluminum tape and they work just fine.  I
understand other folks use them as is and some have put tape on them.  I guess
it just depends on how much work you want to do and what you want it to look
like when finished.  I would expect little performance difference between taped
and not taped.
