Effective application of flat aluminum tape to double curved surfaces?

Ok, I picked up toroidal foam form from the craft store, and
a 50 yard roll of Al tape.  The form is 12" O.D. and 8.5" I.D.
It is made of some remarkably tough stuff, most normal humans
would be hard-pressed to crush or dent it with one hand.

I've wrapped it with one layer of tape, winding it in a spiral
with about 1/4" overlap on each layer.  After rubbing it with
the back of a spoon and wiping off all the black stuff 
(aluminum oxide I presume), it looks about like I expected,
covered in lots of really flat wrinkles :)

Is there a way to get this stuff really smooth, or am I just
out of luck with this fairly tight radius?
