Just checked a tin of Track's Mink Oil I've had for 4 or more years, non-used, however it has been in my shooting box all those years, however
is stored in my basement, in the box and it's only about 62F in the winter to 65F in the summer. Just opened it up and it smells just fine.
I guess you, Bob and Joe were unlucky in your initial purchases. Nice to see that Track would replace it.
