I would like to back up Monona Rossol's comments about theatrical
smoke fluids--although I have no experience with Pro Haze, I have
had bad experiences with smoke fluids in the past.  The constituents
of smokes are sticky and hygroscopic, so when they deposit on
textiles they attract dust, and when they deposit on iron objects
they cause rusting. I'd avoid them if at all possible.
