I have to disagree with Ted; I hunt with all my guns in any kind of weather and they all have Tru-oil finishes. I find it easy to use and with a pleasing satin finish. After the gun has dried from a rain hunt, I rub in a coat of a mixture of 1/3 each Tru-oil, artists cold pressed linseed oil and turpentine. By the way, David (Furman), either you are exaggerating the cold Northeast temperatures, or you mean 0 degrees Celsius.0 degrees Kelvin is the same as -273 degrees Celsius...absolute zero! It doesn't even get that cold here in Wyoming :<).
