Unfortunately, yellowing has plagued the coatings and lacquers historically.
That's one reason I'm very reluctant to use something that does not have
either a good Wilhelm test or other evidence or reputation for
non-yellowing.

Nick, what airbrush system did you find worked best?

A Premier Imaging contact says they've found a CO2 cartridge powered sprayer
that works well, but I have not been able to get a product name from them.

Getting a fine spray with reasonable coverage seems to be one of the tricks
with water-based coatings.  I tried the Preval, but it didn't work.  The
local paint expert is now a fan of Crown's aerosol "Spra-tool" (Aervoe
Industries) for small jobs (and cheap people like me).  I'll give one of
these a try this week, hopefully.  It has different nozzles and more higher
pressure than most systems.  We'll see.
