I was getting some wear on the drivers seat, and the door pull, so I had a local company mix up a custom SEM interior color to match the lighter grey of the 2 tone grey Cayenne interior.

Here is the color mix codes that can be used to match the color perfectly.

Mix in quart can-
Grams
1554-266.2
1559-94.7
1501-80.4
1302-55.2
1550-32.6
1553-3.0

This code can be used to recreate the exact color. I just used a good microfiber cloth to wipe it on with great results. Seats and door pulls look new again. Hopefully this can save others the custom mix fees, or the cost of paying a pro to touch up your interior leather.
