Choose to spray paint an item in a well ventilated area away from anything that could catch overspray. Apply just one thin, even coat of spray primer. Once the primer has set for the recommended dry time, apply 2-3 thin, even coats of spray paint in a continuous sweeping motion 12-18" away from the object. It's best to apply multiple thin coats rather than fewer thick coats to avoid drips or splotches.
