Why not get a roll of this greenhouse film and cover your greenhouse roof panels with it? This way, the UV rays get blocked by the sheeting, protecting the poly panels underneath? Am I crazy?
Been thinking on this since you wrote it. If you meant to cover each panel individually, then no, I don't thing it would work and yes, you are crazy to think I would attempt such a thing. But if you meant to use it as a cover over the sunny side like one would a shade cloth, that would work. Securing it down would be the trick. I don't know if it would be worth the effort because after spring, we get little sun in that area. I am going to think on this a little more. Leaning towards a spray coating but I need to research that still. I am a ways away from that step.
