Spraypaint!

Tips: 

Always spray outside or in a spraypainting booth

Don't spraypaint in the rain

Always put a piece of paper or covering on the ground/table where you are painting. Spraypaint is messy, and the overspray isn't always predictable

Tape your stencil down on the painting surface and cover areas you don't want sprayed with either tape or paper

Hold the spraypaint can approximately 11 inches away from your painting surface which spraying. 

Don't spray too much at a time. You can always do more layers and let the paint dry in between each layer.
