The side bolster on the driver seat of my C43 is just starting to looking like it could crack - i.e. you press the leather in with your finger and and it doesn't flex like the rest of the seat - just starting to look like dry skin! I want to prevent it from it cracking as you often see on side bolsters - any suggestions? It's red leather and I've been using DoDo Supernatural leather cleaner and sealant.
