By far the worst video ever. The program sucks balls, puts a watermark on, and the video was so dark that I basically had to flare the entire thing, but at least it illustrates the motions.

Zebra coating is basically horizontal sweeps of the can in one direction, and then horizontal sweeps in a perpendicular direction. It's important to turn the can 90 degrees when doing your perpendicular strokes, so you're still sweeping the fan back and forth, instead of up and down (up and down will make a FAT, DRIPPY LINE).
If you're using anything you bought at an autoparts store, you will be using a fan nozzle. It produces an almost 2-dimensional fan that is vertical (parallel with the can).

black is nozzle, red is paint.
If all of this is confusing, then it's probably because I'm just too scattered to explain it right
