Advantage Gelcoater
Set Pressure
Turn PUMP PRESSURE regulator slowly until gauge reads 35 PSI.
Spray Test Pattern
Hold the gun about 18 - 20 in. (45 - 50 cm) high over the paper. Pull the
trigger, and spray one three-foot pass.
While spraying, check the spray pattern to make sure there are only slight
“fingers” or “tails” (heavy streams of material). Also check for misting or
fuming.
Increase air assist pressure in 5 PSI increments until “finger”
disappears. Optimum operating air assist pressure is 35 - 45 psi,
depending upon the viscosity of the materials.
