There are two ways to get a smoother finish. 1). Turn up the PSI on the gun. 2). Add reducer as per the TDS instructions. For instance, you could use an HVLP gravity fed gun with a 1.6-2.0mm nozzle setup. Add 15% urethane reducer when mixing RAPTOR. Set your gun at 29 PSI. At a distance of about 1/2 a foot, spray the first coat as an even wet coat. After flashing, reduce the pressure and material flow to achieve a fine mist for the second coat.
