Can anyone tell me what sort of results are realistic with Leatherique? I've tried it a couple of different times on my car, I've let it sit for days, I've covered it with Saran Wrap, I've tried it in the summer heat and winter cold, and it doesn't really seem to do all that much.

Right now, I'm not all that concerned with color, or nicks or scratches, but I would like to recondition the leather to the point where it's reasonably soft again. Some panels are (e.g. backs of seatbacks), some are stiff as cardboard (rear headrests, passenger seat).
