Beat my expectations
Bought a box of old bridles and horse tack - it was dry, stiff and in someplace cracking.  While this won't cure a crack it has made the old leather supple again.  I've had this stuff about a week and I've used half the container already because I've been using it on Everything! Old boots that have seen better days are looking really good again! one of the bridles I bought is usable again, the other..part of it was too badly cracked and weak but other parts have regained luster and flexibility so I can use the parts off it and one pair of reins look brand new, the clips look rusty but the leather looks new.  I'm surprised and definitely buying another container of this!  I have put more than one application on some of the old leather - the better stuff was amazing after one application the much older leather I put a second application on and I plan to put on a third once it finishes drying and soaking in.  I've heard raves about other products but I have to say I'm sold on this one.  It's surpassed my hopes.
