Chainsaw bar oil is very sticky and seals the metal very well, doesn't dry out or gum like WD-40. Whens the last time you saw a well used Chainsaw bar or chain that is rusty, even if it's been hang out in a shed for years. I used to store my guns in a unheated garage and the ones wiped down with bar oil never got any rust, others that got regular gun oil had to be rewipe at regular intervolds to keep rust at bay. Works for ME.
