I use Bohnings White enamel to dip my arrows. Thin a little at a time. Let it sit after stirring for about 30 minutes so all the bubbles rise to the top. Mark each arrow at the depth you want, dip the shaft and pull out for about a minute then dip again. Let dry overnight and then dip in the Bohning Supercoat (Clearcoat). Again let dry overnight. You've now got an arrow ready for cresting or fletching. I enjoy dipping, cresting, and fletching my own arrows. Helps with cabin fever which is common this time of year.
