RE: Spray Cresting help
utah,
The Duco on the gloss enamel works fantastic! I had some in my quiver that had been pass-throughs for five or six deer. That means you've really got to hand it to True Flight feathers, too... all I did was wash them thoroughly to get the blood out of the feathers, let them dry, and put 'em back in the quiver. Occasionally, I would have one tear some feathers up, but that's to be expected every once in a while.
I've never primed before spraying with the gloss enamel, either. Just two coats is plenty.
