I have an old San Marco suede saddle, although the suede has been burnished to sort of a nubuck patina. The saddle is starting to look a bit dried out, and I'm wondering what I should use to treat it. I have all kinds of leather products, from liquid waterproofing (sold to treat goretex hiking boots) to Sno-seal (silicone wax) and lots of things in between. I'd like to protect and preserve without softening too much, and without lots of residuals to come off on my shorts. Any ideas?
