There were some recent posts on the topic. I recently had my leather wheel on my Reatta Coupe re wrapped by Carter Craft of Craft Customs (AKA American Stitches) in Texas. I thought I would call and ask him about his feelings on the slick steering wheel problem. His reply was not a great deal that can be done as eventually all leather wheels will end up slick due to the oils in our skin . He added to slow the process down to keep the wheel clean with mild soap (woolite mixture) and water, and use Lexol.
