Lo and behold ... after making a few normal passes with the spray

spray immediately came out milky/cloudy on the surface of the piece.

(Obviously a _moisture related_ phenomenon - most likely due to the
expansion of the compressed gas changing the relative temperature
(PV=nRT) of the different nozzle passages, then reacting with the hot
humid air).

Didn't last long, but my initial reaction, and remembering this
thread, was WTF??

Guessing here, but maybe close...but a little different. Not so much
moisture related, as simply related to the atomization of the product. When
you switch over, it probably takes a short bit for the nozzle to properly
re-adjust for proper atomization. Just a guess...
