I agree, krylon makes a series of paints that work very well. If you have an "AirBrush" auto lacquer looks best that way. Go to a Craft Store and get some Paint Pens, they come in various colors, they are easy to use for your crest. You can find them in fine, or bold.
Regarding fletchtite, the Platinum works great on most every type of paint I have used. You can use the superglue fletch glues, or the tape. I have had mixed sucess with regular fletchtite, as long as you use a poly clear coat.
I perfer to use a clear satin poly spary over the crow and crest to protect them, and to tone them down a bit so they don't reflect light so much.
Just a note, the wraps, while I use them from time to time, never look as good as a good set of dipped and crested arrows. They are pretty heavy, and can adversely affect the dynamic spine of your arrows. The paint is generally lighter in weight, and therefore has less effect on the spine. I mention this as it is generally an item overlooked.
