Third and cheapest is white spray paint. This sounds stupid but it actually works very well. Simply tape off the arrow where you want the white to stop. Apply light even coats to the shaft and let dry. I spray, rotate 1/4 turn, and repeat three more times holding the can about 10 - 12 inches from the shaft. Let dry for about 20 minutes and then repeat. I apply three light coats to get good coverage. After it has dried for a day take some "0000" steel wool and lightly rub the paint to smooth it out.
