I trailered my car down from San Jose to Las Vegas. It is my daily driver. When It arrived in LV the leather was in great shape. Since then it has started to totally crack and open up. My office has people who come and wash the car. I noticed a white residue on the seats and asked them to stop doing anything to the leather. since then (coincidence?) it has been cracking open. I have tried two different conditioners. One works really well for a while and then it opens up again. Any ideas on what issue is (maybe it is just dry weather?) and how to save the leather?
