If the cracking is bothering you, I’ve used this stuff to cover it up with great success (this is black, the one you want is the dark brown). It’s a perfect match for the coating on my Aero B-3.
Hi. I wanted to ask whether this would work on a sheepskin coat that is suede rather than leather? I have rescued my grandpa's coat from the charity shop but it is in need of a very good clean. Any advice would be appreciated.
