Don't spray or put anything on it, find a Leather shop and have them repair it for you. You trying to fix it yourself can cause more damage to it. I had that happen to both doors, at different times, and the repair work they did is Flawless. My shop told me of the damage that some people had done, trying to Glue it themselves.
