I have a Primos Predator Den ground blind and i wanted to know what is the best way to waterproof it. I am mainly concerned with waterproofing the seams.

I have never done it but maybe Scotch Guard????? I've used it on other things, it might just do the trick.

Use the seam sealer for tentsyou find in the camping department. Works fine.

Put it on a few days in advance of putting up the blind and let it dry. The smell will also go away

Atsko Sno-Seal, you can find it at the camping section of most stores.
