I have a vintage pair of Swedish flight pants. I have used leather doctor products before on sheepskin coats with good results. Hydrator, Fat liquor. The issue with the pants is that I can not gain access to the skin side of the sheepskin as it is covered with a heavy cotton canvas. This is the outside of the pants. Can I use the products mentioned and apply it to the hair side of the sheepskin????? Or is there a better way??

Thank you!!!!!!!!!
