Haven't ever heard of this happening to a thick 18" primary. My 16'' has never, ever dewed up. In fact I am pretty sure that cooling that much thermal mass is more of a problem. Michele Plettstone maintains that a shroud makes little or no difference with dew formation.

But it would keep keys or coke off the primary.
