Answer: I just used Bick 4 on my leather jacket - worked great. Probably going to use it on my leather chair and the interior of my old BMW...
Question (a followup): Does it have a scent? All the conditioners I've tried so far -- Allen Edmonds, Lexol, Saphir, Pecard, etc -- have a scent, which can be kind of strong if you use them on leather jackets.
Someone told me that Gliptone has a scent, but it's the scent of new leather, which is why I'm considering switching.
Answer (to the followup question): It has a light scent on application, but I just went and smelled the jacket - it smells like leather...
Bick 4 is great stuff.
