I would not personally do anything to it. The whiskey tends to spot with anything wet so you don't want to take the chance that it will have uneven color or spot or become darker except for natural aging. The legacy leather is naturally vegetable tanned Vachetta leather and you should avoid rain anyway so I would just not treat it at all and follow the instructions on the care card.I bought the ALI Slim Flap in Whiskey and LOVE IT!! I want to take good care of it and those of you that have the Whiskey Leather how do you care for it??
Have you put Apple Guard on it?? I have some but am afraid to use it on it.
