Choose a base coat color and apply to entire object, let dry completely, usually about 20 minutes. You will probably want to wear gloves while painting.
Choose a coordinating color and spray a generous amount on a paper towel.
Quickly begin to apply the coordinating color over the base coat by lightly rubbing over a small area. Apply more pressure to make darker as desired. This will dry quickly so work in small sections and reapply more paint to paper towel and repeat process until complete.
