Three sets of dryers are used when spraying epoxy paints. One set at the compressor tank & these two sets just before the spray gun. The set on the bottom, with the gage, are actually fastened directly to the spray gun handle. Even very small amounts of moisture can cause clear epoxy paints to become dull & not cure properly. Heated epoxy paints should become tack free several minutes after spraying even though full cure may take 24 hours.
