I dont use a blind often,usually with a new hunter or a kid or on really rainy days.I have a DB and a older primos,and the primos serves me well,especially when cost comparision is figured
in.As far as totally waterproofing one i'm not sure it can be done.mine drip a little in a real heavy rain around the roof seams(primos),but its not so bad it runs you out cuz youre soakin
wet.id say this blind is 4-5 yrs old and has been used 15-20 times and is usually left out for several weeks at a time,and rain leakin hasnt become a real problem
yet.you may try spraing it with some camp dry aerosol,it s the stuff used for camping equipment.
