Hello Orchid Friends - This may be a little late but our enameling
group has also had the discussion of needing a fine sprayer. Many
find that most sprayers spit larger droplets along with the spray.
There is a 2 part sprayer that I’m sure can be purchased from
Thompson Enamels in Kentucky. It consists of a liquid holding
chamber and an aerosol can.
Others have found that olive oil sprayers from gourmet or kitchen
departments work nicely. Since they are made to spray a thicker
liquid they do quite nicely on the thinner liquids. I believe they
work with a manual pump / pressure reserve.
