Hey SoCal, also be cognizant of things like cell phone and other PDA devices clipped to your belt. These can scuff your leather too. Even your pant belt can do damage and I have seen belts do color dye transfer on light leather interiors. Watch for any fancy (metal) belts that your spouse may wear too.
I have been using the leather conditioner from
www.colorplus.com. I have applied it twice since late March.
Happy 4th of July!
