I use "Lexol" that is hard to find but usually Toyota dealers have it. You don't slide and it conditions the leather just right at least for me. I use it for Leather Jackets, leather sofa's and really anything leather.
I like Mothers Back to Black. I've tried all kinds of stuff!!! Alot of these products leave an oily residue which attracts dust and dirt which is a pain to keep clean, also if you get into a light rain it ALL seems to wash away then ya got streaks of crap on the tupperware.
Please let me know when you find a GOOD product!!!
