Lacquer is so forgiving in application, allowing wet coats to be applied with few concerns with runs or sags on 3D surfaces. Further, once applied, there is almost no change in the surface tension characteristics of the wet film, so if the finish did not run or sag at application, it's unlikely to do so as the solvent flashes off...hang it and forget it.
With a full, wet coat, Enduro-Var will initially hang, then may or may not sag or run as the material levels and the surface tension appears to decrease. While runs or sag are easy to wipe off once the finish starts to flash, the area still needs to be recoated and will not self-level to the degree that lacquer will. For necks and other components with a lot of verticals, we shoot and then hang horizontal in a fixture that permits 90 degree increments of rotation to discourage runs and sags.

Spraying thinner, dryer coats is one way to avoid the issues with runs and sags, but given we do not sand between coats applied in the same day, wet coats give better burn-in and reduce the number of coats applied.
Perhaps we've become accustomed to the idiosyncrasies and quirks of lacquer to a greater degree than waterbornes, but it still seems to me that Enduro-Var and High Performance Topcoat are significantly quirkier than standard instrument lacquers. Sort of a Hallmark Channel Christmas movie lead versus the Claire Colburn character in Cameron Crowe's 'Elizabethtown'...but in a less nice way.
