Troubleshooting Chart
If You See: Then:
“Fingers” Check Gelcoat temperature to ensure it falls
within the manufacturers recommended tempera
ture window. Typically, this will be between 60°F
and 80°F. Increase Resin Pump and Air Assist
operating pressure in 5-PSI increments until
“fingers” disappear.
Misting or Fuming Reduce Resin Pump operating pressure in 5-PSI
increments until clean, even, smooth fan pattern
results.
Fan Too Wide Select smaller nozzle angle. Refer to the nozzle
chart provided in this manual.
Not Enough Volume Select larger nozzle orifice. Never use pump
pressure to increase flow or fuming will result
CAUTION
Too much pump pressure or air-assist pressure to the
gun-head will cause porosity in the gelcoat laminate.
