Thinking about it some more I don't believe I would do it. I am a decoy snobby jerk. Meaning I am very (Out of the ordinary) picky about decoys. Brand, rigging, species, placement ect. To the point where my brother and I can go at it on a sandbar if he isn't treating the decoys the right way. My mallard full body spreads are in slotted bags. He will take them out and set them on the ground, just to light my into a pissed off frenzy. That will give you the extreme end of my spectrum. So me personally, no way would I spray clear coat on my decoys. I am switching over to what I believe is the best decoy you can purchase, arguably of course, so I don't have to worry about it.
