Generally speaking for cans, the speed you move your spray stroke across the object will determine how much paint is applied, while the distance determines the texture (by giving the airborne paint paricles time to congeal in to larger particles, or to begin releasing the solvent).

In my experience, spraying from a further distance causes a rough texture.

When I do "Mist Coats" with spray cans, I don't think I change the spray distance at all, and if anything I move the nozzle faster, so that less paint will be applied.
