I was recently given two older bottles of this patch lube called "Blue and Gray". It was made by a company called Blue and Gray Products in Milo, Maine. I can vaguely remember, but I think the friend that introduced me to muzzleloading back in high school used this stuff. It's in a plastic bottle with a fold out nipple applicator. It appears to be in good shape and not drying out any although it does have somewhat of an ugly gray color to it not that it matters. Any of you folks ever used it and if so, lets hear your opinions....BPS
