bowhntr - I don't have a blind but I spray at least one of my camo outfits with a product called Campdry. You can pick it up at Wal-mart. It is a silicon spray about the size of the average spray paint can. It does stink when you apply it but after it dries and airs out there is no odor that I can detect. Wearing this clothing I've had deer right on top of me and not pick up any scent. (Honestly I would bet the Primos stuff is the same thing or similar and you will pay 3x or more for it.)
