To put an end to my input on this subject, I am going to use it this year on my gear. As much as I spend on boot spray and scent wafers another few dollars on UV killer will not break me.
I have seen a TV show on the Outdoor Channel about hunting in ground blinds, and they did, in fact, spray half of the blind in UV killer and left the other half unsprayed...and then turned on a black light. It did glow like a christmas tree. The guy actually covered up the brand name on the UV killer spray and sidenoted that he was not selling a particular brand...but the concept.
It was convincing enough for me to at least try this in my attempt to deceive the whitetail in its environment. I guess if I didnt believe in attempting to conceal myself, I would go hunting in my work clothes and favorite baseball cap.
Anyhoo...I will keep a journal of the success (for my own knowledge).
