Hi, I use a 15 mil (0.015 inch) wire coating rod for gum.  That lays down a wet film thickness of 1.5 ml.  The final dry film thickness depends on the % solids in the wet coating.  I use RDS coating rods, New Jersey, USA.

I wonder if anyone has tried an air-brush for this purpose.  That might an option instead of bull blown industrial spray gun - requiring a ventilated booth.  No dichromate though.  Spraying that would be a no-no under any conditions.
