I use either RTC by Bee Natural (available direct or through Hide Crafters) or Clear Lac (avaliable through Springfield leather).  If I am using the RTC, I will lightly wet my leather, so it will obsorb evenly and slower.  Has worked for me.  I still have Super Sheen, but haven't used it since I found RTC.  My opinion 
Good luck

I just thought of something.  Did you use the liquid and apply with sheep wool or spray?  I have had less success with the spray and it has formed cracks?  Might be something to think about. 
Sorry
