Funny you should mention the shed roof. That was my first thought. However years of roofing experience has taught me better than that
. Second thought was my rifle scope & spotting scope exteriors. Bipod too. I am extremely hesitant to spray anything on my rifle scope (including paint) that costs 1700 American dollars, but I would like something to protect it from moisture while in use. My packable gear is easily covered in a trash bag if needed, but that sleeping bag bivvy cover could use some extra protection
