Hey thx for the idea. I will not try to dye it. I've taken it to the dry cleaners. They will be sending it out to a place that specializes in leather cleaning. So we will see.The only way to successfuly dye the jacket is to go full atomic. Stripped down to the bone with acetone. You'd literally need to dissolve the oil in acetone and bring the rest of the jacket to the same state. It's not fun. It can be done but I don't think it's even remotely worth it. A simple and quick fix (besides what has already been mentioned) is URAD dark brown. It sits on top of the leather and you can feather it into the stain. It will darken the seal? vic to a dark seal.
