I purchased Zaino Z-9 cleaner and the Z-10 for protection. Products smell like leather and have had good reviews on the forums.
You're right time and use will always show creases in seats. I'm currently using cotton tan seat covers, but they move around...I don't think the seat covers rubbing on the leather cause wear. They do help block the sun's fading effects a bit.

The original seats have worn equally, so I don't think I'd use the new driver side one for shows...I'd hate to keep removing them after each show. But, it remains a possibility.
Many thanks for the response.
