Don’t let the condition of your leather steering wheel let down the rest of your interior. You would be surprised by what can be done to extend the life before you need a re-wrap. Here’s a before and after comparison on a BMW E46M3.
Depending on the condition of the leather, most wheels can be refinished in a few hours. The repair involves deep cleaning to remove stains and oils. The surface is then sanded and cleaned again. Liquid leather filler is then used to repair cracked and missing surface leather. The surface is sanded and cleaned again before new dye is applied in many layers. Each layer is set with heat and the new surface is built over time. Once it has cured, leather conditioner is added to offer an additional layer of UV protection.
