I dont think inside, but I havent tried it. Since it's a protective coat, I think only on the soft calf outer leather
Also, what was the concensus on the Bordeaux Blake? I was just wondering about whether or not it needs treating b/c I remembered HitchcockBlonde's comment about the leather being a little stiffer than other soft calf colors
I conditioned my bordeaux blake with Apple...I hope that wasn't bad...
