Don't put on the rough out. It will soak in way to fast. Put on a light coat let it soak in and level. An old t shirt works go apply it. Go light you can add more but can't take it out. To much will make the leather soggy. It will darken it a bit but anything you add to leather even wwater will darken it. After you add the oil let it sit for 24hrs before you do anything else.
