Alcohols, especially larger alcohol molecules are said to be a mild
antifoaming agent. Ethanol isn't considered large with this respect
but if used at such large quantity it may have some useful degree of
effects.

There are several kinds of antifoaming agents, of which I find
silicone oil emulsion to work very well as a final additive. Together
with wetting agent, even coating without bubbles is much easier.

The other day, I found a wide foam roller (8" wide?) saying it's good
for extra smooth finish comparable to spray painting. I can't wait to
use it to coat some paper... (I just got a flat file cabinet to dry
22x30" paper in!)
