Glenn, I basically agree with Marty that you should be able to dial-in your gun by adjusting the spray pattern, air volume, and flow. The best way I know to adjust these 3 vectors is to start off with the flow control closed, the fan set to medium, and the pressure set to 40 PSI with the trigger pulled. Then point the gun at a piece of scrap and: 1. Open the flow control a quarter turn at a time until you're getting enough material to flow on the test panel. 2. Adjust the fan up or down to control the width. 3. Readjust the flow control to make a wet coat that doesn't sag. 4. Adjust the pressure at the gun to control overspray. 5. Readjust the flow control.
