Good advice! I will pay close attention to the seams. I have a small soft brush that will do the job.

I built show cars and Harley's for several years. I used only 303 Protectant or BICKMORE on the interior leather. The 303 works great on tires and vinyl as well. Neither leave an unnatural looking sheen.

I've used the same combination on four Corvettes and my new ZL1.

I'd wager that your owners manual suggests just a clean damp cloth.

Most modern automotive leather upholstery is coated. No conditioner is needed since it will do nothing but create a slime coat on the surface as it can't soak into the leather. Just clean it with something lime McGuires multi purpose cleaner, and maybe use a UV protectant.

Yep, The owners manual (392 pages of it) does recommend the soft damp cloth wipe.
I went ahead and ordered Meguiars Gold Class Leather Conditioner. It has a UV protectant as an ingredient. I will apply it to a small spot when the time comes to clean the leather and see how it does.
Thanks to all who responded. I appreciate the input and advice.
