I've been using Zaino's z-9 and z-10 leather care products on the Porsche (w/ Natural Leather and Ventilated Seats) and I love it. The cleaner is great, and the conditioner leaves no oily residue. I've found if you put a quarter size drop on a microfiber towel and rub it into the towel (so there is no/little free liquid) before applying it to the perforated parts, you don't get any excess liquid in the holes. I also found that if you take your first swipe on a solid surface (in my case the headrest of the seat), the rag is better prepped for conditioning the perofated sections. I would recommend it.
