Blind interior coating
 

I am looking for some help. I am about to build my own pop-up blind. Most of the ones I find do not suit my fancy, are too small or more expensive than what I can build one to suit my tastes. I have two commercially produced blinds now. I like neither of them.
Anywhoooo.....what I am trying to locate is a scent free, scent shielding , shadow reducing, black out coating such as ShadowGuard, Phantom Pro or a similar product. I can`t seem to locate a retailer. If anyone knows where I can purchase such a product , a point in the right direction would be appreciated.
