Comments I have been asked so many times “What is the difference between the Opacity and Flow?” that although it’s not technically a shortcut, I would like to clarify – the Opacity controls the opacity of the paint (is it an opaque metallic or a transparent varnish?). The Flow option controls the speed at which paint is laid down (are you pressing the nozzle of the can of spray paint just a little, or all the way down?).
