I used Eagle One Leather Cleaner.. And Conditoner.. on my 91 Coupe. The seats were a little aged, no cracks in the leather, overall good shape. I applied the cleaner and conditioner in 2001. Followed the directions exactly. A week later after daily use, my leather seats started cracking and chipping. They only did a little bit around the corners.. I stopped using the product and i dont reccomend anyone else using it.
