Picked up a bottle of Floquil primer, last week. It has a very smooth finish and runs through an airbrush with no problem. After running it through my airbrush, I had a first. Most paints tend to build up in the color cup. There was maybe 1ml left in the cup. I unplugged my compressor and was able to clean out the left over paint with the last of the air in the hose. Highly recommended.
