Nice work David703! I do see a noticeable difference in the shade. You can see the brown tint from dirt and body oils. After your process, I can see the clean bright leather. I think it is a big difference.
I hope you found leatherique to be a good product to use as I have. I've tried Lexol, Woolite, and others. They have cleaned somewhat, but always needed to scrub with a brush to get the dirt out of the creases. With leatherique, just apply and let it sit in the hot sun. I found it best to position the seats into the most direct sunlight for the best treatment.
It also restored some of the softness as you've mentioned in my leather from a semi stiff condition. However, it took about 2-3 applications. I applied it so some of my friends cars and they can't believe how well it works. They get compliments from the dealership when they service their cars.
IMO, this is a once a year treatment for me. I still continue to use others on a regular basis.
