It is much more to it. When the paint is sanded and buffed out, there is not much concern over surrounding environment( dust, bugs, etc.) Not so with a clear coating without sanding. To get good surface, there are 2 important factors: air pressure at the gun and viscosity.I have an old viscosity measuring cup, which allows the viscosity adjustment by the amount of time the paint flows through the calibrated orifice. The air pressure has to be adjusted correctly as well. Also the moisture control is important.
