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
